I'd love to see Monolith games come natively to other platforms, but they've absolutely flourished under Nintendo so far. They've been given a lot of creative freedom with their own games, and also have had a lot of success as a support studio on the Legend of Zelda games, Splatoon games, and a lot of the other major games.
They also have a reputation for being one of the better japanese developers to work for, with overtime not normally being allowed. They also seem to give their employees easy development deadlines, with games like Xenoblade 3 releasing several months early (because they finished it early), and Xenoblade 1 remake having extra content, because they finished it early and used the remaining development time to work on other parts of the game.
