The claim that iterators aren't "being used often enough to justify your change" is very disturbing

The claim wasn't that iterators are used infrequently, but the functions in the itertools module.

The vast majority of the time, the only thing people do with iterators is iterate over them.

considering that in future pythons most default functions will return iterators if possible (such as key()/items()/values() of dict).

This is wrong -- they won't return iterators, they'll return views that can be indexed and otherwise used as sequences or mappings. So this has nothing to do with the proposal at hand.
