+1 Smoothness is not necessarily more descriptive than tracktype, and
it may actually produce more disagreement if users skip reading what's
on the wiki.

However, I like that "smoothness" tries harder to cover more transit
types. As the table I posted a while ago shows, both provide more
detail on surface quality in different situations, with tracktype
providing more detail on unpaved ways and smoothness providing more
detail on paved ways.
