So you've heard that we're overloaded, and you know that UEFI is the direction the world is heading.
Well, so is (was?) 'IPv6' ...
Your solution to this is... what, stick our heads in the sand and ignore that? Just do legacy? We already have UEFI-only platforms (see also: the mention of ARM you're belaboring), so that's obviously not going to fly, even if we were willing to, which we're not.
There are enough, different plots of sand for different folks to stick their heads into. To my read, noone's suggested ignoring the future -- rather the suggestions appear to be to NOT ignore reality.
Curious, has anyone from @redhat or @fedora though to actually communicate with any of the 'big' hosting providers, to perhaps coordinate/influence/compromise/plan?
I'd bet AWS, DigitalOcean & Linode/Akamai -- among this biggest hosting providers where 'new installs' would be happening on their VPSs -- would be quite interested in making sure that THEIR customers had smooth install/migration options for Redhat/Centos*/Fedora variants.
I know my _own_ solution to UEFI-install only if those^ providers don't support it; I'm guessing not everyone will have the same goals/approach.
