My entire involvement around Fedora is based on the fact that I was able
to use machines that had been thrown away because they were deemed
‘too old’. I have several servers and multiple laptops that run
Fedora perfectly and none of them would meet this requirement,
effectively ending any chance of using Fedora going forward.
Perhaps as a compromise there could be a ‘regular’ 64-bit and a
64-bit-optimized-for-machines-made-after-2013 version?

Wow. I understand progress, but I have to say that it's not really
cool
to toss this bomb out there without some more detailed breakdown of
the
impact.
For my part, I try to keep my equipment relatively up to date but I
don't want to throw something away if it's still perfectly useful.
And,
let's see, I'd have to toss out five desktops (which isn't too bad, I
guess) and probably forty perfectly functional servers, some of which
aren't really even all that old. Heck, a dozen computational servers
would be on the block. Even requiring avx would force me to toss a
pretty big pile of stuff.
Basically, this would force me to use something other than Fedora.
I'd
have no choice, since it wouldn't work. I don't want to be that guy
with the 20mhz 386 that still wants others to make sure his stuff
works,
but still, this seems like it's going more than just a bit too far.
