@Strazh severa_RU, there will be a new domain or national zone, as you call it: anglosphere.
We are waiting for an option for anglosphere, like AU, UK, and US (and all other domains) have today.
Now we can choose which domain / country we'd like to follow, and by checking the boxes we can all follow different domains /languages.
I guess it will be similar to those.
i was once told how to filter on uk domain for the forum, but i can't remember where to change it to include the new domain, and I can't find the thread where the instructions were in. In fact, I can rarely find anything i'm looking for on the forum. Is there a help section?
