It should have weight if inventory / weight management are considered integral parts of the game, such as offering feats for increased carrying capacity, heavy but good items that restrict your load, dodge penalties, movement penalties, STR or CON based carry / equip weight limits and so on and so on.
Still, it should be something kept for expert mode because today's gamer can't even open a doorway unless it's marked on a compass, has a light trail pointing to it, a tool-tip describing they should go there, an NPC telling them they should go there AND an arrow on the map pointing to the correct direction, as well as an on-screen quest journal that says "Go to the Doorway! It's to the north! Look on your map to find it, then open it by clicking on it!".
Oh, and there's a bright yellow outline around the door once you can see it, just in case.
Bitter? Naaah...
