bug#51062: Customizable window resizing

But what would that accomplish when an application does

(setq window (display-buffer foo))
[...]
(shrink-window-if-larger-than-buffer window)

The 'shrink-window-if-larger-than-buffer' can be inhibited only if the
hook sets something for FOO or WINDOW that inhibits shrinking it.  And
that can be easily accomplished by a 'window-height' alist entry.

OTOH with

(setq window (split-window))
[...]
(shrink-window-if-larger-than-buffer window)

your hook (and the alist entry) cannot inhibit anything.
