Is this project effectively abandoned?

We are using this project but need support for GitHub Enterprise. That means removing the hardcoded values for the service and API hostnames. There is an pending PR #22 that I used as the basis for making the same changes in a fork of this project. However, I would always prefer having those changes go back upstream so they benefit other users, and relieve the burden of maintenance.

So I'm wondering, is this project effectively abandoned at this time? Could it be somehow passed on to the Spring Social project or Spring itself?
