Here's the thing. We aren't an organization and most of us would probably be prohibited from joining such under the usual employment contracts. Nobody is making money from it as is.

The librarians themselves are entirely self organized and basically work independently of the code base developers. They are generally not programmers at all (and don't need to be).

While there are some efforts underway to start slushing around the donation balance we have gained, it takes time when everyone is largely a volunteer with limited time.
