OK.  We really need to be talking about tags, and then sort our opinions
of renderers in a different discussion :-)   I finally get it you meant
to be talking about tags all along; sorry for not catching on earlier.

There is a notion that on highway=residential or higher, no surface tag
implies surface=paved.  I agree that it's better to be explicit.

The fact that the world has changed since the import is another issue.
I was trying to suggest a process that looks at the attributes in OSM
and the attributes in more recent massdot data, and if the OSM
attributes have not been changed since the previous import, update them.

On the east end of the road:

  condition=fair
  there is no surface tag (implying good)

on the west end:

   condition=intolerable
   surface=unpaved

So you are saying that the import added a "surface=unpaved", presumably
because of the condition, in terms of the code written to convert the
massgis shapefiles to osm data.  Now I think I understand.

Here's the information available:

  https://wiki.openstreetmap.org/wiki/MassGIS#Executive_Office_of_Transportation-OTP_Roads_Layer
  https://wiki.openstreetmap.org/wiki/MassGis_to_OSM_Attribute_Map


Overall, I'm not so sure putting surface=unpaved on "intolerable" roads
is so wrong, in terms of how it feels to drive.   But, now that OSM has
more estabilshed condition tagging a better mapping is probably in
order.
