Jeah, I did not state that very clearly. Was I meant was that since they forbid using deprecated methods the (kinda) opposite - future imports - are also not a good idea as mixing versions goes against the zen-priniciple concise and clear.
edit: And what is common is IMHO not an indicator of what is good. People also use cryptic bit shifts, overly complex list comprehensions, etc. all over the place and they are also not good.
But that is just my opinion. But you are right there are cases where you need future.
