Definitely not I would say. It will just cause routing to break down for cyclists IMHO. Too often such sidepathes won't be connected - or maybe the sidepath is not even entered in OSM.
It might not even matter if the sidepaths have been entered and connected. For long-distance routing, I believe that the Garmin Edge 705 completely ignores cycleways for the middle section of the route. Cycleways would only be considered for the first and last 5 kilometers or so. So, if you have a 50-kilometer route that would involve riding on a cyclepath next to a highway=trunk, Garmin Edge 705 would send you on a 200-kilometer detour using smaller roads. I had this happen to me a few years ago. Ways like http://www.openstreetmap.org/way/167517631 were being ignored, and http://www.openstreetmap.org/way/17065902 was tagged bicycle=no already then. That said, I guess that treating more bicycle=* values in the same way as bicycle=no will not make the situation much worse. If you want proper long-distance bicycle routing, you have to use a precalculated route (or better routing software, such as Brouter). Marko
