[talk-au] sac_scale [Was: Deletion of walking

[stevea]

I think as long as "conflates a bunch" is made "explicit" it can be a helpful tag.  This is why I said "generally," as a "rich" tagging as this (which mixes semantics and says "choose a full meal from the menu, not a la carte") can be an exception.  Again, it must be understood that it is a "rating," rather than explicit values that mean specific things unto themselves.

However, it's in use as an official grading system, so it's fine to map it at least in the case where it's officially assigned. Data consumers can decide if they want to use it or use more attributes for each specific trail difficulty variable.
