Why not just follow the original "process"? We "just" changed our infra, not the way we work I guess?
Welcoming someone new is quite normal if they proved active, np with that. So feel free to just start a VOTE thread?
I don't really like the idea of having sub-teams as a standard practice. We don't have that many plugins. IMO, it's just best judgement when working on a plugin: if I want to work on some plugin I know is mostly worked on by another member, I'll sync with him/her to show some "respect", but that's all. IIRC, we always have wanted that any MOJO[Haus] could work and commit on any of our plugins.
IIRC again, we also kind of agreed that in some cases, like Sonar, it might just make more sense to just move the related plugins under the sonarsource/sonar-community GH org. As we said that, if the related org is willing to do, it would make sense that, say, Cassandra-m-p is maintained by the Cassandra team and so on (and also granted the original plugin agrees, goes w/o saying IMO).
WDYT?
