In OoT, there is a limited number of beans, so you have to get all of them. In Skywards Sword, there is an infinite number of treasures.
My stand is like Indy's, if you really think you should collect treasures, then play normal mode. It's like playing NG+, but your character has to be level 1 and you can't use any old items.
For dungeon maps, I'll just follow MM which only required permanent items. So you don't need dungeon maps, compasses, and BKs. I know there's a little contention here for OoT...
You don't need lower tiers of items, since other games follow the same philosophy.
Still unsure about the goddess cubes/chests, because they are not requires in TWW (maps/chests). But I'll agree with either decision, but personally, I support opening them.
Btw, it's funny that the only people who are disagreeing with the current definition are people who are not running the game.
