Combinations is also in +3.0. Otherwise a valid concern. (Been burned by that one myself.) I can't find the source, but there might be some confusion between map/filter/reduce and itertools. Guido does not like map/filter/reduce and wants to get rid of them. Itertools is a huge part of Python 3.0. Everything is an iterator in the language. And the docs underwent a major rewrite with the 3.0 release. It is not going to be deprecated.
