Do you have a more concrete overview of how the change _should_ at least
ideally be propagated for me to get a better overview?

One side-effect of pushing a few set-face-font calls in a
after-make-frame hook in my setup (as opposed to calling set-face-font
once) was a noticeable increase of time required to show the resulting
frame, which is not too nice to have.

In this sense, the change only fixes the lower-level font selection when
opening a face in a single frame, so it doesn't alter how we're
propagating the change at all at the moment.
