Seems to me that this is a specific instance of a conditional, with a 
proposed mechanism for how conditionals would be implemented. I agree 
that conditionals are eventually necessary, probably on an action set 
and individual action level.

You can form_alter the actions configuration form currently by 
targeting form id  'actions_configure'.
