Well, lets see if there are more comments that only will appear once the voting starts :-). If there are, I can rework the proposal. I guess this depends on definition on hiking - I think any recreational walking can fall under it. Though it is a bit developed-world centric as I know in many parts of the world, trails are still used for practical pedestrian transport.
Personally I would not mind removing that restriction. However, I think this is a minor thing and not subject to the vote (it is taken from the current version of the wiki). So I would not be opposed to removing that restriction post vote and independent of it (if there is something like a consensus). Especially if I think this restriction is probably not heeded anyway :-D.
