I believe that OSM should deliver data, and not a service because it's extremely data-demanding. Although I have to say that since OSM offers data, they could make an effort into providing good exports of that data, with better segmentation and choice of format. You should not have to download planet.osm or use some overpass API. The choices are very limited, and offering data through XML is insufficient.
