No different from what what we have with C and C++ every day. It is
very reasonable to have a way to turn the checks off. The question is
how to do it. The optimization you proposed is fairly orthogonal to
that.

My vote so far goes for adding a split_stack attribute that always
turns on the check and then removing the global option.
