The big question. The status quo of the X-Men has been changed to the core. We are still reading the fallout of the rise of Krakoa, and it will likely lead to a full crossover event down the line. But... what will happen next?
Those are superhero comics, and more, it's Marvel. Basically any change to the status quo is eventually reverted, and everything always return to the way Stan and Jack created it, or to the 1970s or 1980s at most. Under that light, Krakoa has its days numbered from the start.
But, on the other hand, it took the X-Men to the roof after decades, and it is the work of one of the best current comic book artists. Such credentials surely help the Krakoan case.
There's also the issue of the X-Men MCU films that will come some day. Will they shift to the Krakoan status quo, or just keep and try to improve the one of the Fox series? Either option would cement or harm Krakoa in comics
