Not to question your thoroughness, but did you test it with all those content types? Also, what about the content type for the OData feed? The reason I ask is when we were setting this up on the old feed, we ran into some oddities with the mimeType mapping seeming to not work correctly. So we fell back to a wildcard for application/* if I remember.
