I see tracktype as redundant with Surface, also very subjective, and not useful.   Smoothness is very useful.

No.

While tracktype= has some issues, smoothness= is more subjective and less generally useful.

Surface= is very helpful and more objective, so it should be mentioned,but I believe it is already suggested on most of the minor highway, path and track pages.

    Do we have close to a consensus that tracktype is not globally
    useful?
    The Key:highway wiki page and map_features could be changed from
    "To describe the quality of a track, see tracktype
    <https://wiki.openstreetmap.org/wiki/Key:tracktype>=*.:
    to
    "To describe the quality of a track, use smoothness=* and
    surface=*.   In some regions tracktype is also useful."

    There is a visibility tag.

    So 'tracktype' should have that removed from its consideration.

    Maintenance frequency ? Yet another tag. And not something all
    that usefull.

    I don't think 'tracktype' is all that usefull.

    Surface .. yes. Relatively easy to understand.
    Smoothness ... yes. Should give an indication of required ground
    clearance.
    Steepness? Yes - the tag is incline.

    Compaction? Not a value I'd use.
    Bear rock that have never been compacted can be harder that a
    road that has been compacted.
    Rather have a tag for 'hardness' that 'compaction'.

    But when it rains .. it can turn a 'good road' (compacted, hard,
    smooth and fairly level) into a bottomless pit (deep mud), or a
    skating ring (wet clay).

    And then there are Australian 'salt lakes' .. a dry hard crust on
    top .. with black goo underneath if you break through.
