Hey there, quick question. In this changeset you've deleted a crossing=no tags at 
https://www.openstreetmap.org/node/432744847/history

I was wondering if this was because a tool was complaining about them?

I've used crossing=no tags to reinforce where there is no pedestrian crossing at an intersection, because I found that pedestrian routers sometimes tend to leave sidewalks and use roadways to cross a bigger street at locations where there's actually no crossing. This usage is also supported by the OSM wiki: https://wiki.openstreetmap.org/wiki/Tag:crossing=no?uselang=en

So if a tool is complaining or not supporting these, that would be good to know.
