So the reason I suggested adding centos10 is that it has a distinctly 
different toolchain from the other containers in the matrix.  The gcc on 
centos10 defaults to generating code for the x86-64-v3 baseline (which 
enables AVX by default) on x86_64 which is different from all of the 
other test environments in the matrix.

centos9 defaults to x86-64-v2 FWIW, so it's kinda unique in that sense 
too.  Fedora does not change ISA baselines the way centos/RHEL does 
since the Fedora community would like to continue supporting the lowest 
common denominator in terms of architecture support.

Although I understand the need to keep the pre-commit CI run slim, just 
thought I'd add my $0.02 :)

Thanks,
