No, you're overseeing something: CIBs don't get merged; one will overwrite the other, and while it is deterministic, I'dn't want to embed that knowledge into the RA. "Merging" is too complicated. And the "I set a constraint on myself" is not in any way identical to "I did something (stop|fail|fence) to the secondary." But that's really the event the master must wait for.
