Another example is the fast travel option with e.g. Oblivion and subsequent games: "don't use it, then", being the obvious response, though in my case it did take a mod to disable it to make sure I got out of the habit of "meh, I can't be bothered to do this".
The worst is actually the slippery slope.
From getting actual directions in Morrowind (since you need to find them), to getting sloppier in Oblivion to just not bothering actually telling where to go, just tell the quest, and let the marker do the rest, in that disabling markers just gets you stuck.
See, "progress" in RPG's.
