Indeed, it may be "too much work" but might be worth the trouble.
Otherwise buffer-local settings for window-configuration-change-hook
simply don't make any sense.

The behavior of window-configuration-change-hook is clearly documented
as being run "once per frame", so the hook function are currently
responsible for cycling through the windows of the frame
if/when needded.
[ This doesn't rule out running the hook twice or more, tho, since we
don't specifically say how careful Emacs should be in avoiding to run
it redundantly. ]
Looking at it again, maybe the right thing to do is to make the
window-configuration-change-hook be treated differently for buffer-local
vs global settings: the global settings are run like now, but we also
cycle through the windows looking for buffer-local settings and we run
each one of them "once per window".
At least for image-mode and doc-view-mode's use of
window-configuration-change-hook, this would do the right thing.
