If a highway is mtb:scale=2 it is definitely not a cycleway. It is a highway=path with mtb:scale=2 If this were to encounter a "cycleway" with mtb:scale=2 , I would consider this an error and retag it as highway=path without hesitation.
I agree, that this is not explicitly stated in the bicycle wiki page, and should be added there, but I would assume that this is the common understanding. Anything else would cause major problems with the huge stock of existing highway=cycleway in OSM that have no mtb:scale tag. Routers for non-MTB bicycles would all need to change and evaluate the mtb:scale tag. There is already a similar problem with the OpenCycleMap rendering in the sense that it renders a dedicated cycle path in the same way as a path with bicycle=yes. This has the effect that many MTB friends have added bicycle=yes to "normal" hiking paths to make them appear as MTB friendly on the map, but also with the problem that when I look at that map I wrongly see a cycle paths where I would never be able to pass with my loaded touring bike. Please keep paths that can only be used by MTB clearly different from cycleways that can be used non-MTB bicycles.
