Yes.  I've rewritten it long ago but it now contains references to
functions based on scaling the body sizes of windows and implementing
these has stalled.  Eventually, 'display-buffer-in-direction' should
replace 'display-buffer-pop-up-window' and its heuristics ...

No.  The "-direction" suffix should tell enough about where the window
should go (incidentally, nowadays many people use side windows for that
purpose).

Sorry, I meant 'dislay-buffer--fit-window'.  Not an action function but
one that would fit or shrink the window and accept the ALIST as extra
argument.  So it could process all sorts of minimum or maximum heights
the user or application wants.

Something like that, yes.  It would end up calling the
'dislay-buffer--fit-window' function mentioned above.
