It can be frustrating to see maps made with OSM data (by big companies that I won't link to here) that omit basic information - like hiking and cycling maps that don't say where you are and are not allowed to walk or cycle.
I suspect that the market for maps that show which pubs that have stone floors is a bit niche (i.e. me), but things like "can I get a wheelchair in" and "which hiking route goes through here" really aren't.
