I've seen gdisk -l output from such systems. I've never interacted
with one. The most common OEM "installer" is just an imager. Basically
it's dd'ing an image, so it it includes all the partitioning and
contents of those partitions, it's not like the Microsoft installer.
It might be that the manufacturer used the same image on a couple of
different SKUs where the only difference was whether they had legacy
BIOS enabled. I don't suppose they ever intended to have a flip from
BIOS to UEFI in the field, but maybe?

Sure. Jump into the deep end. Shout if you need help. Quick like a
bunny though if you want to get it in for Fedora 29.

But definitely start a new separate devel@ thread. This one's
approaching a hijacking. In the new thread you can point out the two
pronged approach, what liabilities there are, solicit liabilities you
haven't thought of. You could cull bugzilla for anaconda and grub2
bugs related to GPT and not booting for hardware models that were
affected, and include that list of models in the kickoff email. Maybe
that gets the attention of would be testers, but also at least puts
people still using such hardware some notice (even in future searches)
should they do a clean install, what problems they might run into. For
testing, it's been six years so it's plausible there have been
firmware updates fixing some or even most of these problems. Perhaps
other GRUB upstream work arounds were discovered.

One big con is the unknown factor, and how to get broad testing
coverage. A contrary position to that is, we didn't know about any
problems six years ago when the switch was flipped, and then we ran
into the problem. So how is it any worse of an idea now than it was
originally? The change is still valid as long as a bunch of people
aren't negatively impacted. Also, it's not change for the sake of
change, it has a followup feature that does incrementally simplify the
layout and makes it a bit more flexible at pretty much no cost.

Yes it is, but contribution in the context of actually changing
inertia means producing the changes: patches, commits, documentation,
tests, bug reports. Things that get much less attention are mere
feature requests without committing resources to producing a tangible
result. And also, this applies to the current spec convo
