Yep; exactly right!

I believe there is a kernel of something useful that can be done here; but we need to be careful about the technical arguments being made.

Well, if we're getting technical, ISO C++ doesn't have compilers either
(at least "compile" is nowhere in `[intro.defs]`). There *are*
implementations. How they exist or work is not something I've seen in
the C++ standard.

And even given what I think you're referring to as a "compiler", I have
no idea what to do with such a thing without a standard library, linker,
or backing platform implementation (because no C++ stdlib I'm aware of
implements `std::filesystem` without an underlying platform).
