What happens when I have a strong mix of =pedestrian, =footway, and ="trail"? In the same park area? Why isn't having a footway=trail subtag (or something) seen as a much more reliable solution? When most of the trails will fall in the lowest tier of the SAC scale, is it merely the presence of a SAC scale tag that tells you it is a "trail?" Would we have to tag a cut-through with a SAC tag to get the way to render differently to show it's status as "below a sidewalk"? It seems to me - as a person who is a Kountry Kilometer away from being data consumer - that using a subtag or similar to let mappers tag trails and other rough footways (the "track" end of footway) is a much more straightforward and direct solution to get trails to render differently than more casual and easily traversed footways found in a city park or rose garden. I am really having trouble understanding the reasoning behind the resistance when it removes uncertainty and confusion while tagging. Javbw.
