I think made for USA is useful - it emphasises that this was a specific - and unusual -
situation. Helps for future proofing in years ahead when we might have a new generation of truth-seekers who won't necessarily be able to pick up some of the subtleties unless we leave clear footprints now which they can follow (which is actually my real message - I don't give a monkey's whatnots about Muranos - but we should always try to embed clarity when we can).

And as a side question - did the US-only years also include CDN??
