The steps will not cause any performance challenge. Bethesda's rendering engine uses your viewpoint, only rendering visible polys. For example, if there is a house or a large rock in the way, the terrain behind it is not rendered until it comes into view.
In this way, you can bet the 7000 steps will not be a straight path. The stairs will wind up the mountain, so that the engine will only have to render a limited portion of them at once.
Moreover, they've already spoken about their improvements in lod scaling. Father-away objects will scale down in polygonal complexity, allowing a vast draw distance with better details and smoother transitions than ever before.
