[js2]

I've been contributing to open source projects since the late 90s. I never found the mailing list workflow awful. I also don't find merging/rebasing/resolving conflicts to be much of an issue, and I say this as someone who spent a couple years keeping my company's fork of Chromium rebased on-top of Chromium. Okay, that was a bit of a pain, especially when a new engineer joined Chromium and decided they just had to refactor an entire subsystem.
