I meant in the message format. You know how difficult this is: the dbus-daemon 
must broker the capabilities. If a message is coming from a service containing 
an extension, the daemon must check if the receiver can receive it before 

When the message is a signal, there may be a big number of receivers to be 
tested. Some may receive the message, others won't.

It would be better if the message format allowed unknown types, which the 
library would just ignore or skip.
