Also, I should have been clearer about the new GC I linked to: I have not seen Mike say anything about it, and I wouldn't be surprised in the least if he rejects it and (wishes to) write his own, because he's had his own plans for many years. It seems impossible to get anything past him without modification. (I think it's a pity to see someone send a PR with a highly informative commit message and he replaces the body with "Thanks to X. #987")

Though, it is possible that he changed his mind after having to review thousands of lines of assembly written by 25 year olds. :)
