No one is obliged to go through every single room in a dungeon if they just want to get their roulette tomes and be out.
However if someone asks "can we go back to X room to get treasure?" I go sure and go back.
If no one says anything, I will just go the direct route to bosses and skip most side rooms.

In regards to stone vigil, most of the side rooms are full of crafting pieces that most people don't care for anyway.
Remember, in DF you're at the mercy of random players so if you want a fool proof "we must kill every guy in the dungeon" party,start a PF group.
