The problem with that is it would require abutters tags and/or be ambiguous as
to what class of highway it is, I also don't think it's a very good idea using
one class of highway for 2 very different purposes.
Some people are using highway=unclassified to mean a wider than residential
road which seems to contradict the wiki reference:
"No administrative classification. Unclassified roads typically form the lowest
form of the interconnecting grid network."
This means to me to mean lower than residential, but the opposite has been used
and some take it as higher than residential.
