WG21's views are not necessarily the same as WG14. It may broke some code,
but it was probably code of the sort that has become increasingly rare over
the years since C++ diverged from C. C and C++ are different languages,
aren't they?

So I think it can be still proposed to WG21.

Not exactly.

On all operating systems except for Windows, the C library comes from the OS 
and the C++ library comes with the compiler, so they are separate 
implementations and have limitations on what the C++ standard can influence on 
the C library, even the <cxxxx> headers.

So this change needs to take into account the difficulty in implementing it and 
evaluate whether it's worth the effort.
