Indeed, I have no objections to your proposal outlined in the email. It's good to see initiative towards re-enabling the qemu-kvm support for the ppc64le architecture within CentOS Virtualization SIG. I'm adding you to the SIG.
There was a prior effort from IBM ( https://cbs.centos.org/koji/userinfo?userID=313). Your plan to start with CentOS Stream 10 and potentially extend to CentOS Stream 9 seems like a reasonable approach. Furthermore, reaching out to the AlmaLinux team for potential collaboration on patches is a positive step that could prove beneficial.
I would suggest dropping an email to devel@ovirt.org as well as there may be people there interested about this effort.

Hi all,
For CentOS infra needs, we have some ppc64le hosts deployed (Power9 and soon Power10) but the existing machines are still relying on RHEL8, as it was the last enterprise distro version in the RH ecosystem to provide kvm host feature. This was dropped after in the RHEL9 version (and still disabled in Stream10 and so for future el10)
I had a look and at least I know that Almalinux people have enabled back what was missing, and so be able to use it as kvm host, and then deploy as usual other guests on top.
I'd like to propose to join myself the SIG and create some tags, just for ppc64le, starting with Stream 10 and eventually (time permitting but not the initial goal) do the same for Stream 9/RHEL9.
Asking so the chair, Sandro, if he minds me (from the Infra SIG perspective) joining the SIG and start some scratch builds as PoC and then promote builds on the mirror network. As said, as we (CentOS Infra) would rely on these builds, we'd maintain these as long as we'd need ppc64le support in our infra, which we don't consider to drop anytime soon.
Opinions, feedback, thoughts ?
PS : trying in parallel to reach out to some folks at the Almalinux side, to see if working on patches can be done in parallel
