Maybe, or maybe not. Routers may adjust routing decisions for each
surface type. Asphalt and sett could be "paved" for rendering, but for
routing there may be a preference towards asphalt roads. Here in
Brazil, taking this into account when computing routes would greatly
improve route quality within cities outside main ways (in secondaries,
tertiaries, etc.). A smarter router could even change this preference
based on weather conditions (under rain, sett gets considerably
slippery, and dirt would be far less preferable than compacted).

[Such a smart router probably doesn't exist yet, but with OSM data, it
can. OSRM has everything to allow such fine tuning.]
