While we moved to Git, we still have the Codehaus Git repository as our reference. Commits there yield notifications on dev@(…) which previously received SVN commits before the Git migration. Lots of us have GitHub clones and collaboration happens through pull requests.
The GitHub tooling is fantastic and this is no surprise that people tend to prefer working there. But as you said each Codehaus project tempted by GitHub shall make it clear that Codehaus is the reference while part of the development happens on GitHub. Cheers
