Yeah, it's something I would entirely welcome, because it would allow
people to control a lot of aspects for which we use various kludges
right now. Perhaps a subset of repo settings, like:


The latter only to specify a subset of snapshots allowed globally, or to
turn them off entirely. E.g. if global cgitrc allows "tar.gz zip" then
the repo can only use either of those or "none", but not add anything
not in global.

Basically, everything that affects how the repository is presented, but
not how it's processed. Definitely not filters nor things that would
significantly impact server performance should they be turned on.

It would be easy to load and parse refs/notes/cgitrc, and the security
implications shouldn't be much different than loading the same from
