FWIW, I haven't followed all the details of this discussion, but it
seems to be about "how do we adjust the size of the frame when some
display elements are added/removed".  If so, then one answer is "never
adjust it".  Of course with frames measured in "lines × columns" this
comes with its own set of problems, but if we switch to measuring frames
in pixels, the problem should hopefully become simpler.
