Sure. "Assuming it's tied to the operating system" is an assumption that
can't be made here, though, if I understand the examples that have
already been given repeatedly regarding numpy and BLAS-linking.

If "OS" were actually sufficient to distinguish all cases, then the
existing wheel platform tags would already be an adequate solution to
this problem.
