Why not simply agree on the criteria for identifying "unroutable roads"
and publish them suitably, so that those who run routing engines can
decide for themselves. It should be trivial to adapt a router's graph
preparation step to ignore routes that match the criteria.

Marking a road access=no without knowing whether it exists or what kind
of surface or access restriction it has in reality sounds not like OSM
to me. If you are so unsure about their existence, then you may need to
simply remove the highway attribute...
