Not yet. Implementing the newer PHP version may take a little bit longer. The GPG key issue should have been fixed; let us know if it is still not working.
Are you referring to updating the admin console to PHP 8? It would be nice. Btw I have a bug report I need to file too re: a dependency for lsphp74 (oniguruma5php, libxcrypt-compat, even libc-client has trouble after removal using repo packages).
It'll be nice to see the admin console updated though. I want to possibly submit a couple patches/PRs for detection/correction of a couple basic things, like permissions. But it'd be best to wait for the update I think.
Regarding openlitespeed repo, I believe it has a dependency on remi's repo too? And is 1.8.2 only on the litespeed-update repo then? If the update repo is like a next or testing repo, wouldn't it make more sense to rename it that? Or to put 1.8.2 on openlitespeed-edge for EL9? Just thinking outloud
