Currently there is really only one, which gets (some) chat but also messages for each and every commit. I don't think the average user needs to see each and every commit. I think we probably need to split these, for instance into Dev and User channels, to match the mailing lists perhaps. )

I’d go even more granular: create a dedicated channel for commits and everyone can decide whether to follow that or not.
