As a contrary perspective, a language which enthusiastically welcomes patches from anyone is likely to degenerate into an incoherent mess very quickly. Language design is difficult. Features interact in complicated ways. Fixing mistakes is tricky - you break existing code. Forking D sounds fine. It's easier to start with an implementation than to go from scratch. Ideas which work out well get to have a existence proof when proposing them to the original. Ideas that crash and fail don't add to the debt of the original language. I hope the fork goes well and this proves a net gain for the original ecosystem.
