Not sure what you mean by “gone away.” At least in production WME they still exist, although we renamed them in the US.
Since no one has spoken up, I recommend that you post draft language on what you would change.
Note for Walking Trails there is also reference to the old terminology with “Waze treats them in some ways like “Dirt road / 4X4 Trail”” that you might want to correct too.
Pedestrian Boardwalk section is blank for me in the current wazeopdia page even though I am signed in.
Just bumping this topic to check: Is anyone else working on this? I could give it a start, if not. I’ve had questions about this from an editor or two.
