One thing I didn't think of (that perhaps all of the old salts have though of): if NR can hunt without a guide, then this more or less guarantees that any sort of access secrecy related to sheep hunting (airstrips, hike/climb routes, etc.) will vanish in a few years. Once-in-a-lifetime diy guys from down here will put up multi-page successful hunt posts full of pics with recognizable terrain. Guys will sell hunt planning a la Bartlett and Strahan for sheep.
