It doesn’t say that--not in my reading. Presumably you are referring to
this passage (in my version of the dbus-daemon(1) man page, can’t quite
find the same version online):

   Be careful with send_interface/receive_interface, because the interface
   field in messages is optional. In particular, do NOT specify <deny
   send_interface="org.foo.Bar"/>! This will cause no-interface messages
   to be blocked for all services, which is almost certainly not what you
   intended. Always use rules of the form: <deny
   send_interface="org.foo.Bar" send_destination="org.foo.Service"/>

The interface field may be optional, but if your code is always
including it, then that caveat should not apply. The recommendation
against send_interface without send_destination would seem to apply only
to a deny rule.
