"regularly" is doing a lot of work here. When Linux drops hardware support, we are talking about ancient hardware. An example of a regular drop: Linux 6.15 just a month ago dropped support for 486 (from 1989)!

Pretty much, you can still get modern distros that support 32bit PowerPC.
That's surprising. What is the 486 missing that Linux needs? Or is it that there are no volunteers to test and maintain Linux on a 486 (as often happens with older architectures)?
It needs a bunch of compatibility code and the maintainers felt it wasn't worth the effort of taking care of that anymore:
