Some optional targets don't seem to depend on when you complete them, but you can still get stuck if, say, for some reason you end up being out of the instance, because you can't go back in.
I'd rather the instance just stay on my list, in its current state, until hand-in, and then I get XP on hand-in. (I assume the reason it doesn't is that people would gain some sort of advantage from doing a lot of quests and then handing them all in or something?)
