I think the best solution = to the SD-6 problem is to take the implementation out of the hands of imple= menters.

Step 1: actively forbid implementations from providi= ng these macros.

Step 2: create a publicly-accessible project that d= oes provide these macros. Each compiler vendor can provide pull-requests fo= r each version of their compiler. If a compiler vendor doesn't do so, t= hen concerned citizens can do the job. Basically, it would be Boost.Config,= but without being part of Boost.

This way, we no longer have to wor= ry about major vendors not complying. Because it won't be up to them.
