I think that is unfair characterization :-)
The proposal was that constructuing a "std::complex<double>" from a
"__complex__" should be written make_cxx_complex(z).

It shifted the complexity to somewhere else without actually seeming
to solve it. That is why I'm uncomfortable with it -- but it is not a
"no way" answer. And it does not seem to be some unique to libstdc++
(at least in the scope of the proposed increaed compatibility with C99).
