I wouldn't say that. Obviously the demo instances for OSRM and GraphHopper use their own vanilla profiles, but other routers very often have customised profiles/rules. My own http://cycle.travel/map has a completely different, much more complex profile than the standard OSRM bicycle profile, for example.

Many motorways in the US permit bikes (on the hard shoulder); it's not uncommon to see a shared-use path in the UK tagged as highway=footway, bicycle=yes; and a short distance pushing on a highway=footway can often provide a good route. For highway=track, I treat it differently for different countries: for example, in the UK I don't route over highway=track unless access tags suggest it's permitted. cycle.travel doesn't currently cover Africa and I have no plans to do so, but if it did I would probably route over highway=track there.
