That was far more amusing and interesting than I thought it would be...

I wonder if it can actually boot DOS on the physical hardware, and if it can't ( DOS itself is very minimal in what it requires of the hardware), is it really PC-compatible anymore?

I'm glad you were amused! I had fun dissecting these images and figuring out what lurked inside :)

Intel phased out the UEFI CSM from new platforms in 2020-2021.

I suppose you could use GRUB and whatever Coreboot has as its BIOS? Either way, sad times indeed when PCs aren't anymore.

seabios is the project you're looking for, and yes now I want to go see if it supports being booted from GRUB:)

EDIT: The answer is yes and it's been done: https://g00se.org/2016/11/seabios-on-libreboot.html (granted, that's booting directly from coreboot to GRUB, but it should be the same booting UEFI to GRUB AFAIK)

Alternatively, we can be happy that some legacy systems actually die when they're no longer useful. My general attitude toward retro-computing is that the good old days weren't actually that good. I, for one, don't care if the original meaning of "PC" passes into irrelevance.

Hell no. We're being pushed into draconian closed systems, this is starting to infect the PC, and it's only because there's little opposition.

As if BIOS is any more open than UEFI is. At least UEFI had an open reference implementation since the beginning. BIOS had to be reverse engineered from IBM's implementation AFAIR. Besides, two wrongs don't make one right. BIOS was a clutch from the beginning (it was probably appropriate for the time tho) and we should strive for better. We should keep functional systems working of course (e-waste is a real problem), but we shouldn't keep using it for the new stuff because we see the past with rose tinted glasses. Rather than push for the past we should push for the future, for having all boards ship Coreboot and have that support upstream instead. That's how you achieve openness, not by sticking to _proprietary blobs_ of an outdated interface.

The Clover bootloader designed for Hackintosh is able to boot UEFI operating systems (including non-Apple ones) on computers that don't natively support UEFI. Is there any reason a different bootloader couldn't do the reverse?
