Great! I'll surely count on your expertise, Matthijs. I think the guys at
the design list can help us arrive at a good visual style for this. We can
start with our 2 cents (malenki's suggestions seem like a great starting
point).

I agree with Richard, here on the tagging list we should not be concerned
with rendering specifics. However, for me it's been great in understanding
which factors seem more important to most people across different cultures,
in order to establish the major difference at the right spot. A rendering
decision requires an insight in tag semantics, and in this case also
involves a tagging culture change (promoting a specific tag) that may even
spread all the way down to editors such as JOSM and iD.

If nobody disagrees, I'll consider that the tracktype tag is the best
choice for this decision, and that any value besides grade1 deserves some
marking meaning it's not in what most people consider "good condition".

I believe an effective way to get people to use tracktype that way is,
beyond a wiki update, also an update on JOSM's presets (in this case,
simply adding a tracktype field in several presets). Experient mappers
(most of those using JOSM) will quickly get the message and then pass it
along to new users.
