Sometimes mountain bike tracks are evident as such on the ground due to track construction and common usage, but have no signage or other indication that they are for use by mountain bikes so I think mtb=designated would be a mis-step in that case as it says it's officially designated which it's not. Secondly because you might have other highway types like highway=track which are signposted as for use by mountain bikes you'd have highway=track + mtb=designated, but it's still a highway=track not a singletrail mountain bike track. Are there implications for pedestrians, riders and "other" cyclists? > Motorbikes?

Personally I'd assume foot=yes, bicycle=yes, horse=no, motorbike=no as defaults where you only have highway=path + path=mtb.
