One of the things I’ve learned from 20 years of OSM is that whenever you say “no one is going to use this”, someone always comes along and proves you wrong.
(There have been many times in the past that I’ve been wrong about something to do with OSM, but blithely assuring Steve Coast in a pub in 2005 that there was no need to map dual carriageways as two separate ways was probably the wrongest I’ve ever been.)
