As far as the idea (glibc-hwcaps) is concerned, both are pretty much the same. I think https://gitlab.com/x86-psABIs/x86-64-ABI/-/jobs/artifacts/master/raw/x86-64-ABI/abi.pdf?job=build is a good read. It's fresh and it might be appropriate to read it first before entering the deeper discussion. If Fedora manages to maintain baselines, the downstream might follow (CentOS Stream, RHEL 10). I don't think it will be mainstream the other way around. Also if production started it might be hard to push such a huge change ¯\_(ツ)_/¯.
