19603	footway=* instead of sidewalk=* on roads	Famlam	team	"[https://wiki.openstreetmap.org/wiki/Key:footway The key footway] is quite often incorrectly used when (in most cases, most likely) `sidewalk=*` is meant.

Perhaps it is an idea to make the validator complain about ""disallowed"" `highway` values combined with `footway=*`? (Formally it's allowed on `highway=footway/path/construction` only, although it seems quite a common tag to use on `highway=cycleway` too)

If not, then it might be worth adding a check for `footway=*` without `highway=*` tag (or prefixed `highway` keys)? [https://overpass-turbo.eu/s/WDM Overpass-turbo]"	enhancement	new	minor		Core validator			footway sidewalk
