APPEND will only do what I had in mind if the hook you want to be
after is already in the current list of hooks.  It will not work if
that hook is added later.

Imagine the situation when foo-hook wants to be after bar-hook but
before baz-hook.  You cannot do this with APPEND, unless the order of
adding the hooks is known in advance.
