Hi Carsten, thanks a lot for your quick response... I thought that there was a small notice in the spec, but I cannot find it anymore: Can I rely on the fact, that a component is fully activated before any service calls are made to it?

The SCR implementation registers a service factory on behalf of the component. Only if someone is requestion the service from the registration, the component gets activated. This is in order to support lazy creation of the component. Otherwise SCR would need to activate all components and maybe only half of them are used. The service gets unregistered first and then deactivate is called, assuming that the component has been activated in the first place. So if no one is using your service, nothing happens wrt your component.
