I agree.  Making the display margins shareable is a tough nut, it will
most probably require introduction of quite a few new functions that
every user of the margins will have to consult.  If the only use case
that needs that is these two modes, and if their problem is only with
splitting the window, let's instead try to solve that on the
window-splittable-p level.
