Hi Steve,

Yes!  we are overloading the cycle route to not simply mean this is a way
to get from A to B but also to mean a good way to cycle there.

So, yes, we are giving two meanings to the same tag.  Yours is simply
navigational, and mine assures a minimum level of amenity in urban areas.

I'd argue my use adds substantial value to a router.  Your use adds little
value over a pure shortest route algorithm.

Ian.
