Argh, there's a problem: an action doesn't have a (directly) associated
 block, and all the TC offload machinery nowadays is built around blocks.
Since this action might have been used in _any_ block (and afaik there's
 no way, from the action, to find which) we'd have to make callbacks on
 _every_ block in the system, which sounds like it'd perform even worse
 than the rule-dumping approach.
Any ideas?
