How about: don't buy affected CPUs if you care. The last thing people who write libraries should care about is a few selected CPUs that underperform on a generally useful feature.
Nope. At this point given the state of the market, and given what AVX512 does to begin with (so maybe the "at this point" will be for forever), it makes very very little sense to use it everywhere. It would just be actively detrimental to most users.
