Yeah, there is a lot of freedom, it's pretty similar to how an open-source project works. Pierre-Loup indicates what features would be nice to have (in gamescope or other projects), I can pick from that list. Or I can pick my own ideas and work on these. Or I can discuss with the other contractors, come up with an idea and coordinate our work. Sometimes I work on short-term bugfixes, sometimes I work on long-term plumbing efforts.
