Yes, that's what listening for D-Bus signals is all about most of the time (getting notified when something of interest happens, which can happen at any time, hence there's no real possibility to unsubscribe). IIRC D-Bus signal filter/receiver rules are checked in the D-Bus daemon, so moving most of the checks into the rule instead of checking for simple things in the callback reduces the wake-ups, right? It's not something that we can do automated, but it would be nice to add some info on how to write good, powerful match rules to the relevant "power saving" Wiki pages. For example, is it possible to compare parameters of D-Bus signals in the rule (say, the second parameter is equal to "disconnected"), so we don't need to receive signals that we won't process/need anyway?
