Though you can't really currently say something is not a hiking trail.

This is what the wiki says too "exposed sites may be secured with ropes or chains, possible need to use hands for balance". Anything that doesn't need hands, but has a fall hazard/is exposed would be sac_scale=mountain_hiking (assuming it's not alpine).
