I just realised this created an "unresolved thread". Apologies for the noise...
Just a thought about proprietary applications and/or binary packages that are in the repos (e.g. Steam, Discord, Opera, ...) - this might be an opportunity to move those to their own "non-free" or "partner" repo. I'm not sure whether anyone really cares about the difference, but then again it might be nice to know that the "main" repos are solely built from sources.
There are a few variants around "Community" which would reflect the role's responsibilities around the community repo and AUR (e.g. Arch Linux Community Package Maintainer).
Ubuntu has MOTU for their "community-supported" Universe repos, so maybe something that has a nifty acronym (e.g. ALPACA)?
