Do you think it would be simpler and thus more reliable
to enforce height constraints such as min-height
in fit-window-to-buffer?

This will be very clear to users to see how it works:

  (pop-to-buffer (generate-new-buffer "*edit string*")
                 '(display-buffer-below-selected
                   (window-height (fit-window-to-buffer 10))))

where 10 is min-height.

Because it should be the task of fit-window-to-buffer,
and it already has the argument MIN-HEIGHT.
Also other arguments of fit-window-to-buffer
could be allowed to use in display-buffer-alist.
