I agree migrating is painful, and supporting both even more so. But not because of print. Migrating print statement usages and even making them work on python 2 and 3 is trivial, even fully automated and statically verifiable.

Compare that to unicode changes, where you need to manually inspect and potentially deeply analyze every single string literal.

Why waste resources making the trivial easier just to please people that will not migrate anyway?
