You mean the value of a 'window-height' entry could also be a

        • A list whose CAR is a function and whose remaining elements
          are the arguments passed to that function.

so we'd run

            (ignore-errors (funcall (car height) window (nth 1 height) ...))

in 'window--display-buffer'?  Which means the caller has to know the
function and which arguments it needs in which order.  Sounds fragile.
