Comment (by jorbin):

 I modified @wonderboymusic's patch to add a few more @ticket references in
 the unit tests.

 Looking at this more, I think it might make sense to mark everything as
 final, at least initially.  It's easy to remove final, but damn near
 impossible to add it back later on without breaking things.  As hooks are
 the foundation of the WordPress API, I think it's important that they work
 consistently across WordPress installs.
