User blog comment:Brandon Rhea/How we're testing the fandom.com domain migration/@comment-24361909-20180928215953/@comment-20644-20180928230300

Using domains like fandom.pl, fandom.hu, and fandom.de would mean we'd have to purchase a ton of new domains. That's costly and has a lot of overhead to maintain all of that on one site.

I don't think there will be any problems in terms of international communities losing independence or being treated like translations. If that assumption isn't currently being made for pl.starwars.wikia.com, we see no reason why it would suddenly be made for starwars.fandom.com/pl.
