I've browsed through the search and found plenty of topics about gpg signinig and the like, but no mention of modular streams anywhere. While yes, they were removed from Fedora 39, they still made it into RHEL 10 and are by far the best way to distribute different versions of a package with commands like

dnf module switch-to php:remi-8.5 to upgrade from 8.4 to 8.5.

Are streams supported in any way?
