it never makes sense for a government to mandate how private companies should design their products, other than for safety, which is not what
this is about.
it's also a proposal. it may not happen.
it wasn't that long ago they wanted to mandate micro-usb, which would
have been a disaster.
in a few years, another connector will replace usb-c. then what?

While I generally agree with that principle, it comes about from a wish
to reduce waste (a good idea)
with the unintended consequence of making
life much easier for consumers as well as allowing manufacturers to sell stuff cheaper with no charger.
Electronics companies *could* have got
together and agreed standards to make chargers more interchangeable, but
they didn't.
it's also a proposal. it may not happen.
it wasn't that long ago they wanted to mandate micro-usb, which would
have been a disaster.
While it isn't the greatest connector, disaster is a bit strong. I guess
50% of my stuff is micro usb, with about equal quantities of mini and -C
at the moment.
in a few years, another connector will replace usb-c. then what?
Probably, but it's a pretty good connector (and conveniently reversible).

there is very much an issue because people will need to replace their existing cables, docks, accessories when they upgrade to a new phone
most people hand down their old phones to their kids or other family
members, so they still need to keep the old stuff around.

it's currently a proposal and will likely change before it's finalized.
keep in mind they want to mandate using a connector that is nearly ten
years old.

actually, there were numerous complications.
in addition to what's listed above above, add dce/dte, null-modem

since the signaling voltage varied from +/-3 to 15v, some devices would

few pins were needed, so they used db-9 instead of db-25, resulting in adapters, or they used a custom non-standard adapter.

no it isn't, other than for legacy devices, which area extremely rare.
Cisco routers,
some networking equipment does have a console serial port, but that's
one of the rare exceptions. it's also legacy and not normally needed.

Or the Raspberry Pi.
the raspberry pi does *not* have rs-232. what are you smoking?
depending on which pi, there is usb, ethernet, wifi and/or bluetooth.
the pi zero has *only* usb, although it does support some usb-ethernet adapters without drivers.
it's possible to use one or more pins on the gpi expansion port for
serial communication, but that is not an rs-232 port.

You can add dozens of interfaces to RP or Arduino, but they don't come
"with" them. Further, the serial ports on the RP and Arduino are
different voltages (from each other) and neither is directly RS-232 compliant.

Learn the difference between what you can add to a pi and what it has
out of the box.
The pi does have serial data level ports at 0 to 3.3V. But that is not,
at all, RS-232. A RS-232 receiver might read from the Pi. But sending RS-232 from a device directly to the UART input on the Pi could result
in damage to the Pi.
Nobody suggested 'native'.

Maybe, maybe not. In the Cisco training I had, the first initialization
of the router had be done always using the serial port.
If you read docs on flashing normal routers with alternative firmware, several of them you have to access via a serial port, after opening it
up to expose the pins; in some cases the pins do not exist, you have to actually solder the cables or solder a connector. Just 3 pins are
needed. You need that because those routers are not intended to be
flashed by their owners and do not expose a function on their normal management interface.
I have a friend working with security hardware, and often his routine includes connecting to the machines via serial ports. One of his grudges
is that modern laptops don't have it, but he needs it. Has to use an USB
to serial port converter.
My own desktop machine has both a serial port and a parallel port in the board. Bought recently. It is used for kernel debugging.
for example. Or IoT gadgets.
such as which ones?
Ask google, it said so.
in other words, you made it up.
No, I did not made it up. I knew of it, so I googled for confirmation. Contrary to you, I don't know it all.

You found 9, 15, 25, 37, and 50 difficult to differentiate between ?Really there was 9, 15, 25 and 37 way and a 50 way which I never got to use.

Then was it crossed or straight was DCD used , then there was busy ackwThat's not the connector - that is one particular use and protocol
and x-on x-off and many other pins that I've luckily mostly forgot about. all just for 8 bit communication, of course have a standard 25 pins when you only really needed pins 2,3, & gnd
did seem a bit wasteful expense wise.
being put through it.
I just don't think govenments should have much say in these sort of areas.Agreed.

Complain to google :-p
Learn the difference between what you can add to a pi and what it has
out of the box.
The pi does have serial data level ports at 0 to 3.3V. But that is
not, at all, RS-232. A RS-232 receiver might read from the Pi. But
sending RS-232 from a device directly to the UART input on the Pi
could result in damage to the Pi.
Nobody suggested 'native'.

It was a standard, just that some failed to implement the standard
correctly.
not a very good standard since there was a substantial amount of
variance in how it could be implemented.
It was pretty much all there was at the time. So got used for all sorts
of things.
