isn't avx-512 one of the more poorly supported set?

It's on every amd cpu from zen4 onwards, every remotely recent Intel server cpu, and now again on intel starting with nova lake this year.

In the future, it will be everywhere.

I think the issue is that Intel skipped avx-512 for a few generations, meaning that you can't rely on it being available on your compile targets
