Yes. I agree with that. Particularly because early adoption has shown
that for this to be useful (in the environments where it can be used,
which is not everywhere), the semantics have to be that of an
"optimization" to be performed by the build system, and at this point
I believe the specification goes farther than it should.

The thing that is necessary for achieving this optimization goal is
simply to allow the implementation to use such a mechanism, we don't
really need to introduce an entirely new set of semantics to the
language for this to be possible.

The introduction of the extra semantics means that this optimization
becomes a required part of supporting the language, and the argument
I'm making is that this optimization cannot be applied universally.
