Thanks Josh!
that means that if I wish to move beyond Centos/rocky/rhel/etc. 9 it will be time to upgrade the hardware.

I'm just wondering how (or if) AMD processors map into this issue...
The v1, v2, v3 baselines are defined based on the x86_64 instructions available within that family. AMD CPUs certainly fall into this, and you can see an overview here:
https://en.wikipedia.org/wiki/X86-64
Not just the recent (last several years) CPUs, but earlier ones that
implement AMD64, such as the Vishera (which I'm still running).
Whatever it is doing, Rocky 9 64bit seems to run fine on it, but I
wonder how I will fare in the future.
As best I can tell, Vishera is a v2 compliant microarchitecture. RHEL 9 has a v2 baseline so Rocky 9 working sounds like what I would expect. The v3 baseline bump would mean that specific CPU won't work with ELN/CentOS Stream 10/RHEL 10. v3 starts with circa 2015 or newer CPU models.

Yes, I wasn't expecting v1 to return for RHEL 10, I'm just wondering
if
we can give v2 a bit more life.
We plan on moving forward with the v3 baseline change.
