It was only an idea based on observing that on my high res screens
the full width minibuffer seems overly generous.  Hence my imagining
side-by-side windows.

Honestly, I do not have any real appreciation for the implications of
"only one min-window per frame" assumptions.  My thinking was
that the two side-by-side windows would be children of a single full-
width internal window which would in turn be a per-frame singleton.
This per-frame internal min-window would contain the per-frame
mini-buffer input window and the per-frame echo area output window.
