in practice its often simpler to compiler to C and leverage the incredible
number of man-years put into C compiler optimizations.

Alas, C can't guarantee proper tail calls, among other issues that make it a fraught compilation target.

I think the issue with C's heritage is overblown, especially considering
that modern compilers support pre-compiled headers.

GCC's pre-compiled headers are not pre-template-instantiated headers. If most of your -O0 compile time is template instantiation (as mine was), precompiled headers do not help.
