I hope this means that PGF/TikZ becomes hosted on Github – I think the team there does a great job and the concept of “pull requests” really fits any open source project, no matter how hard the criteria for patches are.
Sadly not. If I put their code to GitHub, this doesn't mean that GitHub will become their primary version control system. I would use it just to simplify packaging of ConTeXt distribution. However: - it would be a convenient place for pgf developers to see which patches are needed - patches would be tested by ConTeXt users - it would be much easier to keep track of changes that are needed - we could use the bug tracker to keep track of changes that are still needed - Aditya or anyone else would be free to play with more ConTeXt-like code; pgf developers are not all aware of modern coding style in ConTeXt, but if they received a ready solution, they might accept it
Untested (but this is really simple code, so nothing should break) https://github.com/mojca/pgf/pull/1 Aditya
