I can also say from direct experience that (1) it doesn't get very much funding, and (2) they take plenty of external suggestions and contributions.
A key thing they do is offer finer-grained roles[1] for project and team (i.e. subteams within an org) management.
You're right that they don't provide namespaces, yet. I believe there's ongoing discussion about how to enable that, including via PEP 752 and 755.
