Agreed. One can use the surface tag to do this together with "SAC_scale" 
etc (with which I'm not 100% familiar but do understand the general 
purpose of)

So

bicycle=designated; surface=rock; highway=path

for some of the bridleways you get in upland areas would indicate that 
bikes have a legal right to use it, but might not want to.
