This is a minor technicality. It's like saying that cars manufacturers
like Honda have nothing at all to do with tyres -- even though every
car gets 4 tyres.
There was a time when people said "C++ doesn't know anything about
threads", and we changed that to reflect reality.
The C++ Standard already acknowledges the existence of a compiler and
how it should behave (e.g. issue a diagnostic), and so it wouldn't be
a big deal for the Standard to say that we can specify options to the
compiler (since we're all doing that already anyway).

The real world is already like this though. "-pthread" is just one
example. Part of the evolution of the C++ Standard is observing how
people in the real world are working with the Standard as it changes.
