Its a good point. The pressure on open source devs for far less popular or important projects is often to much for those devs. If you think about your code affecting the monetary security of so many people I can see it being something few would desire. That said, this is why a project has to have thorough code review processes (which bitcoin has) and a community providing support for core development. I think we need to admit we are in uncharted waters here. I can't think of another software project like bitcoin in existence.
