Sorry, I should have spelt that bit out. I'm assuming the winter road
consists of many segments, which will be of different combinations:
some will be "highway=track", some may be nothing (ie, outside winter,
there's really nothing worth noting), some may be "highway=road,
surface=unpaved". Route relations are good for this kind of situation
too.

If that's what works best for your local mapping community, then sure.

IMHO "don't map for the renderer" does more harm than mapping for
specific rendererers ever did.
