Ok. So I'll revert these changes since it seems a majority is against 
them. And if YODA is so close, I agree that it wouldn't be worth having a 
version which behaves differently for a month or two.

I feel similar here. If I knew what I could do to get YODA running 
earlier, I probably would spend time on that instead of interim solutions. 
But I would appreciate if these plans would contain at least rough time 
scales, such that I know what and when to expect (and whether I do need 
(private this time) interim solutions).
