The Pentium Pro came out in 1995. This is dropping support for CPUs that came out before then. The 486 came out in 1989.

I personally think 36 years of support is long enough.

There were 486 compatible SoC chips being released as late as 2010.

I think you can still buy them: https://www.vortex86.com/

Do they usually run a Linux kernel? I would have expected some RTOS on a chip like that. And if it does run Linux, does the SDK use mainline Linux or some fork by the manufacturer?

They run Windows CE and Linux though they also support QNX.

Specific Vortex86 detection was added in Linux 5.15 I think
