A brief survey of my hardware and less than half of it supports avx2.
I can't find a single enthusiastic endorsement for this proposal in this
thread, so far; but if this proposal ends up being adopted, I hope that this
gets announced well in advance, including a big fat banner on
https://www.fedoraproject.org, to give everyone in the community plenty of
time to make their own arrangements, in liue of that decision.
