Yes -- for a variety of reasons, I don't think this is a good candidate for inclusion in ELPA or Emacs itself, but should stay as a standalone package (added to MELPA whenever I have the time or somebody else does it).

Strictly speaking, there is no dependency on Google at all in the package: it should work with any "XOAUTH2-compliant server." In practice, however, Gmail is the only reason people need support for XOAUTH2 authentication mechanisms, so it's a moot point.
