Also to be more controversial. - redhat deprecated x86_64_v1 & x86_64v2 . and people were crying because of that....
Don't see how that's controversial. It's something that doesn't matter to their customers or their business.
Oh, -v2 is deprecated for RH10. Not a big deal, honestly.
From a fleet perspective, I prefer more code uses more advanced instructions on my processors. Efficiency goes up on hot code paths possibly. What's not to love?
Did you mean v3?
If it has seen any decent amount of workload during its lifetime, it possibly has a couple of ICs which reached their end of their electronic life and malfunctioning.

tl;dr: AlmaLinux will support v2 in EL10 as a separate rebuild in the near future.

We even do a full EPEL rebuild for it as well.
This is also same on the personal level. I use the OS which is most suitable for the task at hand, and the root OS (Debian / RedHat / etc.) doesn't matter. I'm comfortable with all of them the same.
