Oh yes, of course, forgot about that one. I do also mark what surface type the forestry roads are (surface=ground is what I normally put, but surface=dirt would equally apply), but that is intended to tag what type of material the road is made of (asphalt, cobblestone, gravel, dirt, etc). The key "smoothness" and its competitor "surface:condition" are intended to be for how "rough" a road is (eg. what would be minimum wheel radius or vehicle suspension height to drive on it). Surface:condition has been used 20 times so far :) The key "incline" [1] might be another useful one for 4x4 roads.
This is just another example of how OSM's tagging system is open to flux and is not set by any one person. The point, I think, is to tag as much as you accurately can, and if you can't (like if you don't know what mountain biking scale a trail should be, what smoothness it is, or you forget what surface type it was), then don't worry about it - someone else can do it.
