I don’t think so. Maybe just about DK but unlikely. Anyone in eurozone doesn’t go. Anyone in Schengen probably doesn’t go. Anyone with big inflows of money or big outflows of workers (A10+2 essentially) has no interest in going. Hard to see who else it could have been.
I suppose SE an outside chance as well.
SE going on an anti immigrant and "we can be like Norway next door" platform plausible (Agree no one in the eurozone goes, not sure Schengen is a barrier given Sweden de-facto abolished it's Schengen compliance years ago)
Did it abolish on SE/NO border too? That could bite. As well as not having EU rights when arriving at foreign airports.
Sweden is part of Schengen. Sometimes Sweden has passport control checks when coming in from another Schengen country. In the last 3 years, I rarely encounter the checks when flying into Sweden from another Schengen country; but I encounter them occasionally when coming in by surface transport.
