I have the problem that a way is usable in one mode of travel (foot) and unusable in another (horse).
I verified with the debugger during import that all flags are zero for the horse encoder, the edges only get a forward and backward flag for foot encoder.
But during horse routing, the ways are included in the route anyway.
My solution still uses graphhopper 0.1, so I know what the obvious suggestion is. 
But my question is: Was such a basic problem ever found and fixed somewhere in the version history of GH?
bye, Nop
