Currently the use case is not as much for Plasma desktop as it is for another project, suffice to say that there are no plans for usage of this service on desktops yet. On desktop, however, the service could be made self-killable-when-idle and dbus-started-on-demand. I can't say how big the mem footprint would be for some thousands of contacts. For about 500 it's ~15MB. There's certainly room for optimizations ;)

However loading all the datasources and populating the model can be slow and speed is critical in this case. Therefore it's a dbus service which responds very fast and there's no need to initialize anything as it can be loaded in the background after system starts and it keeps itself always up to date.
