API is always simplification and is not supposed to be used without understanding concepts and reality under the hood. Example: wanna show 1M POI in browser on some small territory. Openmaps/googlemaps API allows that, no prob. Looks good, yeah? Sorry, doesn't work. Because 1M is too large to show and browser gets stuck. The API do not prevent _all_ kinds of legshooting engineers invent.
