If he puts a dungeon crawl in another place than deadly traps, he needs to publically justify deadly traps, (and he would have put in a dungeon crawl without reason—remember that (at least) most insane things he does have a hidden reason). If he puts the dungeon crawl in the same place as the deadly traps, he can claim the latter to be part of the former, and it would stay “a thing that Dumbledore does”, so long as nobody actually dies.
He doesn’t have to tell anyone about the deadly traps (that are separate from the dungeon crawl) - they and the Stone are supposed to be secret. If Voldemort can’t even find them, so much the better.
Since he doesn’t admit publicly that there are deadly traps, his public justification of the dungeon crawl is the same no matter if there actually are traps or not.
What he needs a reason for is putting the dungeon drawl in the same place as the deadly traps.
