"... particularly regarding surface firmness."

In contrast, on Map Features it says tracktype is "To describe the
quality of the surface".

The maintenance frequency of a road is not directly observable, so
it's good if this tag is defined in a way that relates to the road
itself.

This was the original description for grade5 in early 2008:

"unpaved track; subtle tire marks, lack of hardcore, Soft with low
grip, subtle on the landscape."
https://wiki.openstreetmap.org/w/index.php?title=Template:Map_Features:tracktype&oldid=71778

Until July 2018 the grade5 description mentioned that the materials
should be "uncompacted":

"Almost always an unpaved track lacking hard materials, uncompacted,
with surface of soil/sand/grass."

Should "not compacted" be added back to the description, perhaps?
