a new model for open source: closed to pull requests, open to remix.

For what's the point of reading a pull request that's been generated by code? All I want is to read and understand the core idea. If it's a good idea, I might incorporate it back upstream, but there should be no expectation that I will. You see, open source software is open source by definition because the license says that it's as is, and that as is permits you to remix software.
