Well, I don't know. Just like exp parties benefit from not cramming too many people into too few camps, NM campers benefit from knowing how many campers are there. There's more than 1 NM in the game, so not wasting a trip to realize it's just not worth the bother is a good thing.
As for HNM camps... I can see happening... ways to cheat the system... I can already think of a few. Though it would be useful for people lookin' for a Peacock Charm, a Bat Cape, ext... 1 a day NMs only really that are soloable so people don't put LS resources into finding their times.
Of course since it's just an option, people camping VE or whatever can just keep it off if they don't think it benefits them.
