Comment (by sc0ttkclark):

 I should note that the developer will probably need more than just
 changing the action name, they will want to also include logic to check if
 their action has already been run to prevent it being called again when
 multiple blocks have post meta binding on and in other use-cases which
 have `get_registered_meta_keys()` called on the same page load.
