What does the Python Software Foundation and the community think about this?

I have to agree - but what you are really saying is that without Christoph, Python on Windows is
*really really really*
not viable.

I don't know if he'll ever read this, but if he does, thank you
Christoph for your amazing contribution to the community.
The fact that we have a problem now is a testament to the length of
time that we *didn't* have a problem, thanks to him.

What’s the problem now? Is it with python on windows? I use python on windows so I’d like to know. Thanks

Python itself is fine, but a lot of third-party packages are hard to
obtain. So if you need numpy, for instance, or psycopg2, you might
need to find an alternative source.

obtain. So if you need numpy, for instance, or psycopg2, you might

Both numpy and psycopg2 have binary wheels for Windows that can be pip installed from PyPI.
Certainly for the more widely used libraries like numpy installing
binaries with pip is not a problem these days on Windows or other
popular OS. I notice that psycopg2 *only* provides binaries for
Windows and not e.g. OSX or Linux

need it simply works. "pip install numpy" works, same for psycopg2,
pillow, pandas, and other packages I use. Conda should work too, for
those who use the Anaconda Python distribution. I honestly don't even
know how it's done: are there some kind souls who provide the wheels
(binary packages) for all those things, or if there is maybe a build
farm that does the hard work to make things easy for us.
In the past I've used Christoph Gohlke's site and I'm very grateful for
the service it provided, but these days I don't really need it anymore, luckily.

The deal really is, the instant a new Python version drops (3.11, 3.12,
etc.) a million people rush to install it, some of whom should know
better and be more patient. 3rd party packages are their own projects,
some have binary wheels ready on Python release day, some soon after,
some months after.
You can hardly blame a lot of people for doing this. A seb search for "download python" gives this as the first hit: https://www.python.org/downloads/

I am guessing that the release process automatically updates that page
so that the minute 3.12 gets released the big yellow button will
suggest downloading 3.12.0 as the default option.
Perhaps it is really package authors who should be getting a release
out that is compatible with Python 3.12 before 3.12 itself is
released. It's tricky though because as a maintainer it makes more
sense to wait until you see the finished 3.12 product before making a
release that is fully tested with it (even if you are testing the
alphas etc in CI and making incremental fixes before 3.12 is
released).
The other option could be changing the downloads page so that it does
not suggest 3.12.0 as the default option until it is clear that at
least some baseline of widely used packages have uploaded compatible
wheels.
Sadly Windows is still in the dock. The jury is still out.
Turns out the "without a hitch" was based on cached wheels.
I'm going to start from scratch with new projects using Pythons 3.8,
3.10 and 3.11 and report back.

Report summary:
pip install works well with Python 3.8 and 3.10 (and presumably 3.9) but
3.11 fails.
Report conclusion:
As indicated in this thread, pip cannot find Python 3.11 wheels and
therefore needs to compile from source. It is looking for Microsoft's
C++ compiler version 14.
I'll (gulp) attempt to swallow the Koolaid.
See error below ...
