An interesting idea.  The one concern I have is that users really won't
care about writing hooks for most things.  For any sufficiently sizable
change, users will want to write subclasses, not hook implementations. 
If you can develop an argument against that, I see no reason why we
shouldn't write a generalized "hookable tool generator" that does all
the work for us.
