If so, not a problem, but please confirm. Either way works, but given syzcaller could potentially trigger these holes (it did find a whole bunch of 'interesting' problems in the early noinstr days) I'd prefer them earlier rather than later. OTOH, the objtool patches that keep triggering them all over the place are still in objtool/core for the next cycle.
