That's what graphic-only for `pop-up-frames' is used for. But this
option is ignored in the fallback case (unless `pop-up-frame-function'
wants to check it).

As I explained elsewhere you can make `pop-up-frame-function' do
something silly, so the frame is not created in the worst case. Hence,
I would have to say that `pop-up-frame-function' has to behave
reasonably in that case. And I would have to enlist the windows
`display-buffer' tries to reuse before trying to pop up a new frame and
maybe some other things I never tried to understand.

That's a correct conclusion, indeed. The "creating a new frame" part
would then have to sidestep `pop-up-frame-function', obviously.
