You're right that there's no right or wrong answer. What I meant is
that I don't know if what you call "program control" should be the
responsibility of the text-scaling code (with suitable hooks to allow
customization), or it's better to leave it as it is and let the
applications (like linum.el) adapt to a possible rescaling.

As it is now, an application has no way to know that the text in the
buffer is shown rescaled/remaped, unless it periodically checks
`face-remapping-alist', because remapping does not *have* to go
through face-remap-* functions, so there's no hook or callback.
