The more cynic part of me thinks it's because Marvel still believes they got the goose that lays golden eggs here, which they can use as it with minimal effort or care, hence pushing it as great new status quo for the X-men, while to me the whole thing is build on such a shackey foundation (i consider it valid possibility that Hickman never intendet for this to last beyond his run and that it might have been designed as cautionary tale in first place) that it now more than ever requires a lot of care and work to actualy become sustainable in some form.
So now they try to promote this status quo as perfectly natural state for the X-men to be in, while the paint is allready peeling off on the eggs.
