Overall, this seems like an improvement to me. However, I note that the translation on the wiki mentions trail markings several times, while the original German SAC text doesn't really mention markings at all. Instead, SAC mentions trail visibility several times. In OSM terms, the following is roughly true: T1 ~ trail_visibility=excellent T2 ~ trail_visibility=good T3 ~ trail_visibility=intermediate T4 ~ trail_visibility=bad T5 ~ trail_visibility=horrible T6 ~ trail_visibility=no Note that both T1 and trail_visibility=excellent can be achieved without any markings whatsoever. I think it would be best to remove the mention of trail markings in favour of links to trail_visibility. Alas, I haven't found a good way to express this on the wiki. Also, some T4+ trails out there have excellent visibility and some trails that are otherwise T1 have horrible or no visibility. The SAC scale does consider trail visibility. But should sac_scale=* consider it as well, and if so, to what extent? > [...] > > Let me reiterate that the subkey that's needed is actually the one > that asserts 'this IS what one would expect of an urban or suburban > footway', rather than 'this is a relatively unimproved "natural" > trail'.
