If it is legal to proceed in one direction only shouldn’t there be one way only tagging on the individual ways that make up the hiking route?

But for a route relation, these tags mean something like "the bus/tram/train" really IS going in a certain direction, so from really is from and to really is to.

I can imagine that for some technical reason I am not imagining (a sheer cliff, something making it ostensibly or actually one-way) that this MIGHT not be true, but then that's technical hiking, I suppose: you can go this way or that way and your necessary equipment might be quite different in the other direction. Or it simply "can't be done" or "isn't allowed to be attempted" or "I can't get permission to blast steel pins into the rock" or "that ice can't be climbed...". Then, there is free soloing El Capitan, so, who am I?
