No strong opinion there.

We definitely could, but a warning may very well go unnoticed at the
user's place. And it leaves open the question of when the warning should
turn into an error : at some point a developer will use a feature and
not turn the warning to an error.
Beside the decision to default to c++11 **now** has not reached
consensus afaik, although we know it will happen sometime soon.
