The whole point of the future statement is that it should be harmless once you're in that future (unless the future feature ends up retracted -- think of it as an alternate universe, a side effect of time machine misuse :-).

Although there could be a warning (off by default) in 2.3 or whenever to let users know that the code is no longer needed. People tend to cut & paste and reuse code from others, without always knowing why. Noops should be culled from code as a general rule =).
