There are no stats available that could be considered defensible. At
best, we could come up with some estimates based on the stats from
other sources that we might assume have a similar profile as Fedora.
I'm not sure if that data exists anywhere, though.
My main personal machine also lacks AVX2-capable hardware, so from a
personal perspective, I'm not super keen on this change. I'm
privileged enough to be able to upgrade my hardware if required, but I
recognize that it's not a reasonable request for others.

I think we need to see some actual benchmarks demonstrating this. For
the core kernel and system libraries rather than microbenchmarks or
specific applications that already sport AVX codepaths.
I agree. It would be good to see some more specifics about what the
benefit will be. That's the only way we can decide if it's worth the
