I wonder why? Surely any flight plan sent to Eurocontrol goes to all the sector controllers? What exactly is it that achieves the implicit enroute clearance?
I'm not aware of the system enough to be sure but I think you'll find that the main reason an off-route IFR plan goes to Eurocontrol is so that you can be sent a bill for route charges if they are applicable to the flight. As for going to all of the sectors - I don't know about ACCs (which are where 'sectors' are usually controlled from), but I don't think a plan will find it way to a CTA or TMA unit that way.
