These writers aren't Claremont. They will never write "like" Claremont. That's not to say what they've written is bad or lacking (I would argue quite a few runs have actually been better than those "classic" stories).
Whereas Claremont wrote with the understanding that he was shaping these characters for decades to come, Hix-Man and Co. know they have a three/four year timeframe in which to write the most engaging stories with ALL these characters, the best way they know how which is NOT the "Claremont way".
The days of big, sweeping single character arcs and development are long gone where-as now the writers are building on what came before in smaller increments. Nightcrawler's "big character scene" (so far) came in the X-Men Crucible issue. We know how he feels and what he thinks, in the context of the larger story, being in this case Krakoa/Moira's 10th life....and it's up to HiX-Man or someone else to build on that...if they feel so inclined.
Even Storm's "big development in 2021" is not going to be as big as Claremont's development of the character throughout his decades-long run. And it will be up to the writers after HiX-Man and Co. to decide if they want to build on it, or not.
Also consider, these characters under Claremont were already pretty much very well-developed and three-dimensional and it's up to the writers now to explore those developments (as Hix-Man did with Nightcrawler, as they might do with Storm) to the best of their abilities and intentions.
