Maybe [NoInterfaceObject] as well?

Using [NoInterfaceObject] may break existing applications as
FileError.NOT_FOUND_ERR (and other constants) will not longer be accessible.
Constants will only be accessible on FileError instances.

Good point.

My goal was to get people of off FileError. Maybe add a DeprecateAs to the
interface (I'm not even sure that works)?
