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.

Cheers for the reply. By "quality control process" do you mean manually checking bridge height restrictions, recent road closures etc..., or do you mean something more automated such as filtering out badly formatted data?

its mix of both. I don't think full automation is possible at the moment.
