To be clear, the only thing that's "stalled" is integrating large pieces of code into our nightly builds. People are certainly still working on developing their bug fixes/features/etc.
That's why I said "stalled" and not "halted" or "stopped". I'm surprised the discussion is around the wording of the title, half of which is your choice of wording, rather than the content. It's an interesting thing that a major open source development effort has hit a road bump in development, and the steps to solve it are interesting.
