Longterm zfs support for RHEL 9 and clones

[deajan]

So I run a couple of Almalinux 9 servers and am stuck as all RHEL9 clone users with OpenZFS 2.1.x branch.
This makes sense for long term support, but it seems that some bugs like #16019 and #15772 weren't backported to 2.1.x branch (the only ones I am aware of, sorry if not relevant perhaps).

Since RHEL 9 support is going until 2035, and since developpment of OpenZFS 2.1.x branch isn't probably going until that date, would it make sense rebase RHEL 9 OpenZFS version to the current "legacy" branch when new branches come out ? (Eg rebase to 2.2.x as 2.3.x should now be stable ?)

I'm aware that I can just enable zfs-testing repo, but this would render some other software ecosystem (like RSF-1) incompatible, since editors usually just follow the official OpenZFS releases for RHEL.

Perhaps I am making a false assumption, but this should also lower the maintenance burden for old releases.
Thanks for any insight.
