Or am I missing the point of the edge, does it serve more purpose than just a coloured edge as an identifier?
The green edge was (and in the EU still is) to easily show your eligibility to use the blue customs lane (as opposed to the red ./ green ones). Customs officers could / should stop you if you are / were in the blue lane without a green edged label.
