I think we agree: hiking_exposure=* was proposed but I think it would be too bothersome to tag with so many tags, and won’t help with getting these quality tags used by data consumers.
The trail is indeed going through a mostly dry river bed: it has other parts where you have to climb on top of big boulders using your knee first, so I’ll keep it sac_scale=alpine_hiking for that part and reduce the ford part to demanding_mountain_hiking. I already added safety_rope=yes and will change the ford to stepping_stones
