 you can come up with a different name concept? :)

 Hm, interesting. In both cases, that name would make sense.

 In '''this''' case, I could think of something like `ensure_action()`...
 Not sure. Also, there's not really an interest in this at all, considering
 both the ''impact'' opening this ticket has had, and also the plugin API
 is not really young, and yet noone ever really seems to have needed
 something like this...?
