MusicBrainz already stores data that is legally incorrect, for example, Label-Recording Phonographic copyright.
This is nothing compared to that, IMO.
But if you insist that Style would say that [Worldwide] shouldn’t be used for digital releases that are known to not be available in a couple of countries because those countries have their own version, then I’d rather Style ban the usage of countries on digital media releases available in more than 50 countries (arbitrary threshold) rather than require editors to list 180 countries on the release. (The community has already been informed/requested to stop listing 180 countries on releases due to performance problems anyway!)
I’ve mentioned it years ago, but I didn’t find a ticket for it, so I also created MBS-13031.
