We should consider renaming the tree repository in Fedora and CentOS Stream/RHEL, and leave the + packages alone. We've asked for fixes in gitlab to support the proper naming including '+' characters.

There are other source packages that don't match 1:1 with their dist-git repositories, so I'm not sure how much trouble a hard requirement would cause.
