I wish more would use self hosted solutions like Forgejo (or a gitweb if they don't need a complex system) and simply mirror their projects on codeberg and github for the exposure.

Gentoo apparently do it that way already:
https://gitweb.gentoo.org/repo/gentoo.git/
https://codeberg.org/gentoo/gentoo (mirror)
https://github.com/gentoo/gentoo (mirror)

please everyone get the fuck off shithub kthnks

If only there was some other choice
