Except that it is of benefit to the C++ community if the C and C++ layer are
compatible beyond just syntax. N2178 defines interoperability semantics that
go beyond standard pthread.

I would agree if we were talking about 2 substantially different APIs. Sure,
if you have pthreads and something that's somewhat different, why not. The
point is that pthread, with a few extensions, is exactly what we need from
this hidden API.

But let's turn things over: why not use pthread instead of creating another
API? I think it is clear that using pthreads has a few advantages. What is
the drawback?
