Thank you for reading and hopefully answering. :)

If the internal storage is a hard drive as opposed to an SSD, then
there's nothing weird or odd about it. Physical shocks should *always*
be avoided with hard drives, because the read/write head floats only a
few nanometers above the spinning platter, where even what we might
think is a /slight/ shock can send the head crashing into the platter
("Oh noz, my HD crashed!"). And the hard drive isn't the only sensitive component in a computer, either. With a hard enough jolt, there are
other things that can go wrong.

In general, you should follow this simple rule: be careful with your
expensive electronics if you care about them.

I don't know that it's supposed to reboot. It's meant to park the heads
on a hard drive so that there is less chance of the drive being damaged
in a fall. Of course, it's pretty much useless with an SSD equiped Mac.

It was covered in either a product announcement for the aluminum MBP

True, which why it's pointless on SSD-based Mac laptops. You can
actually turn it off, but it's probably not even worth the effort.

Yeah, something else could break from the sudden jolt, drop, etc. Might as well play safe!

You said a 2012 MBP, so that machine was designed for spinning hard
drives, though SSDs were an option.

As the wikipedia page states, it only exists in machines that support
hard drives (though the page says laptops, and I think that is not
accurate, but I may be misremembering.

There are no other moving parts, so there's nothing else the sensor can
be used for. It is solely for hard drives (inlcuding Apple's Fusion
drives). It's not possible to stop the screen getting cracked or hinges breaking, for example.

the sudden motion sensor is in macbooks (and the older powerbooks and
