Well, at least for some proxy classes I suspect that it is important to 
know if a service is running or not. At least one proxy (the GLib one) 
does cache the property values and simplifies connecting signals to a 
DBus object. If the remote server is killed but remains activatable, the 
proxy needs to know it to invalidate the cache; and when it is launched 
again, it needs to know it to reconnect the signals.
