Before we go any further, we need WG14's opinion. The value for C++ alone is
very close to zero or even negative if C doesn't adopt the same. C++ could be
convinced to follow C for pointers but nowhere else if C adopts your proposal.

So please approach WG14 and propose that they adopt this. If they seem
agreeable to considering it, WG21 can comment on whether it is for or against
the feature. But if WG14 simply says it won't, the point is moot.
