Another question is how to deal with messages to some interfaces (such as org.freedesktop.DBus.Introspectable) on the receiver side. There does not seem to be a good way to create receiver rules that would allow receiving of messages to certain interface on one service and deny it on other, as there's not destination-based check for receive rules.
