We have no control on what each hook could or could not do.  We give
programmers a rope, but cannot prevent them from hanging themselves
(and take down Emacs with them).

E.g., what happens if two buffers displayed on the same frame have
different hooks there, which just happen to have conflicting ideas of
what should be done when windows are resized?  How will they be able
to reconcile their conflict?

Makes very little sense to me.
