Gokd moaning ;o)

Interesting read, has no effect on routing since its tagged on a stop spot point rather than a junction crossing seen often in the US. A OSM wiki conspicuously absent, it is a tag part of a preset with all and minor as options. Curiously, checking taginfo/overpass, the use is plastered all over Italy, a few actually on a crossing, unlikely, where traffic light are often mapped , AND the rest of Europe. AFA Italy is concerned, think the tag can go, absent of any effect on navigators, albeit here, obligatory stopping is rarely abided by, all driving with a little angel on both shoulders. So please remove this excess tag
