LOL - not a bad set there. You mentioned a European Standard and as the EU made fools of themselves with bananas this could be one area where the Commissioners dare not set foot (and thank God for that with such unelected and overpaid meddlers wasting everybody's time and money).
The French have hygiene standards against shorts in pools but some water parks go the other way where speedos might offend young families on their day out - so it all really boils down to "when in Rome......"
Btw, vids for the Rotterdam swim are pretty poor so the simulated one (no speedos) might be better to see the round-the-island course if anyone is interested:
