I agree, and that's the strength of linux, but here's a slight devils advocate:

If someone is heavily invested into RH for their BIOS only infra, this could be an issue for them. I'm sure there's large operations that would need fixing up if these change happens.

Not that RH is obligated to cater fully to that crowed of course. But 10 years is a bit silly, especially with how expensive hardware is now due to covid.

All that said, it's not going to be an issue like everyone is making it out to be.

Individuals should have few problems forking mainline to keep BIOS support, and large organizations will be given amble time to upgrade (at least years. RH isn't stupid with it's corporate customers.)

RHEL has a 3 year cadence, so if (if) RHEL 10 makes this change it won't have been 10 years, it will have been 13 years.
