Guido: How come the deprecation didn't happen in 3.10? Were people just not interested?

Well, if nobody deprecates it, it's not deprecated. It is simple as it it :-)

IMO it's ok to only deprecate it in Python 3.11, unless Pablo *really* wants to deprecate lib2to3 before just Python 3.10 final.

I dislike adding new warnings between a beta1 release and the final release :-( In my experience, it *does* break projects which care of warnings.
