No, regional egg hatches were only during the the kanto ultra bonus. And at they, the regionals weren't region locked, i got Kanga and farfetch'd from US gifts.
Currently all 7k egg pokemon are either alolan forms (most of which have not been released in the wild) or are baby pokemon, which flat out dont appear in the wild. When the egg comes from has no affect on what it holds, on distance when it comes to trading and trading medals.
EDIT: currently there are various hoenn pokemon in 7k's, these may be hoenn event specific egg hatches, we do not know yet, but will after the event ends.
