But see, if that is the case... Apple is a large company with lots of resources and knowledge of their internal roadmap. If it took Apple's own internal developers until now to remove their dependence on Python, then third-party developers and their users should get at least until next fall anyway.

(I'm not defending the use of Python 2. I'm arguing that, as a general rule, if something takes the vendor X time, users should be given X + Y time.)
