It is okay not to prompt when there's no need.  That wasn't the part
on which I commented, AFAIU.

I'm saying that no, it will not be useful to prompt in that case: if
the only frames left are non-client frames, we should not prompt,
because we don't prompt when there are no client frames to begin with.
Apologies if I misunderstood the use case.
