Very nice, this was very helpful.

On irc we also discussed signed git pushes (which are now also enabled
on sourceware). Which provides another "layer" of integrity.

As reply to our fosstodon post
https://fosstodon.org/@sourceware/110629743586988452 someone from the
tor project posted an overview of "Git repository integrity solutions"
they wrote up for their project:
https://gitlab.torproject.org/tpo/tpa/team/-/wikis/howto/gitlab#git-repository-integrity-solutions

It references this discussion, so now I am completing the circle :)

Cheers,

Mark
