How is making new installs (and thus re-installs) not removing support entirely?

It's not a hard requirement. Fedora runs just fine on slower hardware. I have an x86_64 1.66GHz Atom machine from 2010 which is still perfectly serviceable as a router, just as it was 12 years ago. I expanded its memory, replaced hard drives, and it's still running. It's BIOS-only. I would not appreciate having to throw it away because of this change. I already had to say goodbye to a couple of Atom-based netbooks that were x86 32-bit but still in working condition because Fedora stopped supporting this arch. > Like the already accepted Fedora 37 change to retire ARMv7 support, > the hardware targeted tends to be rather underpowered by today’s > standards, and the world has moved on from it. ARMv7 retirement is irrelevant to this change, but "the world" hasn't moved on from it except maybe for your part of the world. Please stop generalizing. > Intel stopped shipping the last vestiges of BIOS support in 2020 (as > have other vendors, and Apple and Microsoft), so this is clearly the > way things are heading - and therefore aligns with Fedora’s “First” > objective. I've always understood Fedora's "First" foundation to be "First to implement new features/standards", not "First to stop supporting legacy stuff". If 2020 is the year when no new machines are built with BIOS then give it at least another 10 years for the old hardware to die out. > == Feedback == > Dropping legacy BIOS was previously discussed (but not proposed) in 2020: > https://lists.fedoraproject.org/archives/list/devel%40lists.fedoraproject.org/thread/QBANCA2UAJ5ZSMDVVARLIYAJE66TYTCD/ > > Important, relevant points from that thread (yes, I reread the entire > thread) that have informed this change: > > * Some machines are BIOS-only.

All these points are valid (with the exception of migration, which is possible, but difficult). However, I'd argue that now is too early to remove BIOS installation support. This could be revisited in a couple of years, but right now the feedback you're receiving is overwhelmingly negative. > == Benefit to Fedora == > UEFI is required for many desirable features, including applying > firmware updates (fwupd) and supporting SecureBoot.

Freedom Friends Features First - this is > that last one. This change fails to uphold three out of four Fedora foundations and even the fourth one is questionable in this case. I can understand the benefit of reducing maintenance burden, but don't pretend it's to uphold Fedora foundations.
