If you would prefer to keep using imp in IDLE to make management across versions easier I'm fine with that, just understand my goal is to deprecate imp in Python 3.4 (but won't remove it until Python 4 so people can write Python 2/3 compatible code, much like you with IDLE). So if you're okay with using a deprecated module then this change is strictly not necessary and I can just silence any deprecation warning in the code instead when the deprecation comes about.
