A great dev gets out amongst his user community and finds out the real feelings of those who are using the software. The great dev tries to understand the actual user requirements (not just what has been supplied by the design docs). The great dev listens to the criticisms of the users and discusses what can and can't be done.

I don't disagree with your "great dev" qualities but there is more needed to make a "great dev". Otherwise all the documentation, code ease, mentoring, being a part of the team, etc. is not going to make the code useful to anyone.
