I have a feeling that this "made up name/category" will be a pretext for fast-tracking whatever they want to do with Canada-EU relations without the other members voting on it since the last one they tried to do is 10 years on and still pending.
If getting this status helps simplify process and costs of EU<->Canada military procurement, then it will be a clear win for both sides given the current desire to reduce dependence on US defence providers.
There is no "they" in the EU that can do anything that isn't also constituted either equally or proportionally by each and every member.
