There was a proposal under discussion the past few months on building x86-64-v3 packages for Fedora 45 while retaining x86-64-v1 packages.
The hope was building the Fedora packages with x86-64-v3 where AVX/AVX2, FMA, BMI2, and other newer ISA features can be assumed in the name of better performance.
Unfortunately, the x86-64-v3 plans are now delayed but may be reconsidered next year with Fedora 46...
