Please don't tag them highway=unclassified unless they really are
unclassified roads. Tag them highway=unknown or highway=FIXME or
something. "unclassifed" doesn't mean the OSM editors haven't decided
what they are, it is the real legal status of small countryside roads in
the UK that the government hasn't classified.
