well, the other weren't cat so...
Imo, not translating is a lot better than what we had in the removed chapters.
those were so blended you can't even read the numbers.
Anyway, the monster behind the door plot point should be interesting. Maybe something that will trigger some plot far into the future.
Since the capital has S-class adventurers, someone might be able to reach the Door Dragon... but maybe some cult will have a way to distract or open the door without fighting the dragon. (And when the door opens, the snake can deal with the dragon.) But in the future, Moss Cat could be more powerful than the Door Dragon.
There's also the empire invasion plot point. Gale Wind will probably get involved in it.
