Does this mean the bus does not enforce the correctness of the D-Bus
introspection metadata?  That's really unfortunate.  Classic D-Bus
does not do this, either, and combined with the variety of approaches
used to implement D-Bus endpoints, it makes it really difficult to
figure out what D-Bus services, exactly, a process provides.
