Comment:

 Worked through this with @Veraxus in cha today.

 Let's discuss implementation on one WordPress asset type (posts), and
 whatever we decide to do there should trickle down.

 I think we should add these actions inline, where the form handlers
 already exist. Refactoring `WP_List_Table` is a non-trivial and perhaps
 separate effort. That can happen even after these hooks go in.

 Please review a proposed approach in attachment:16031.diff, and what a
 plugin's implementation with this looks like in attachment:16031-plugin-
 example.php. Feedback welcome :)

 We add a form submission handler action for plugins to tap into, a filter
 for the sendback URL, and allow plugins to add bulk actions.
