There has to be some give and take between all of the uses for OSM. Changing PA to a trunk may work for vehicle routing purposes, but it may not work for bicycle routing purposes.

I would not focus too much on routing outcomes, but more on whether produced
road structure is sane/reasonable.

Note also that mapping more info about road will reduce impact of such 
assumptions based on highway=* value.
