IIRC, this did come up during the discussions in the Forum, with the conclusion that since it didn't affect most users, only tool builders, they'd have to change. As Marc-Andre notes, for the C wrappers and const, there is a very low tech solution which is not too bad.
Fortran is another story. I'm very concerned about the amount of effort in both implementation and testing that appears to be required.
