Complaining that Anderson movies feel like Anderson movies seems almost to miss the point: do we look at Picasso's works and complain about the consistent style he developed? The self-imposed constraints of his own style give him a framework to build his art from (it's often said that constraints foster creativity after all) and a particular craft to master.
Conversely, the form might always be an Anderson movie, but the function of each film can be quite different. By sticking with and mastering a particular aesthetic he frees himself to explore things besides aesthetic wildly. What does The Royal Tenenbaums have in common with, say, The Grand Budapest Hotel, besides Futura?
That said, I do feel like Asteroid City in particular was a stretch for him: there's nothing quite like "you can't wake up if you don't fall asleep" anywhere else in his filmography. It felt like along with the more extreme artifice came a more extreme intensity of feeling: to me it's a film that really came from a very anguished and grieving place. I haven't read the article or seen the new film yet, but based on the headline it sounds like this might be the overall direction his work is heading.
