You are correct about ingesting the osm data directly to something like Valhalla. What had in my mind when I mentioned "usable" is the data after that will be the output of some sort of quality control process. As you said, osm data will have quality control issues (being a crowd sourced) and organisations will want quality checked before the data is fed to their internal systems including inserting to database or to a routing engine.
