This can be rewritten to increase code coverage by testing the success criteria, not putting fails all over the place just-in-case

This is incorrect, the requirement, as i understand it from discussion, is to not call the completion block when cancelled (but to call the other behaviours to let them know of the cancellation)

this can be more efficient, if any return false there is no point processing more

Not sure if this is valid. We don't know what it is in the other behaviours and whether they know about this implementation detail. We also didn't discuss if one behaviour returns true and one returns false, what should we do? E.g. a logging behaviour.
