You lost me here.  What I'm suggesting is to add a hook that's called
when some variables are modified.  So to me it sounds just like advice: as
long as you don't use this hook, Emacs's behavior is unchanged.
And just like with an advice, if you use such a hook in your ~/.emacs
you can shoot yourself in the foot, but if you use this is one of your
package, you might shoot the foot of your users.
