As for the "no duplicates" rule. While it's clearly unfair towards clones who developed into their own identities or alternate timeline duplicates of characters who are stuck in 616, it's a rather sensible rule given how easily a liberal stance towards cloning or duplicates could be misused or radically alter the society of mutants towards the worse.
The mutant society of Krakoa is allready heavily geared towards only giving those who have "valuable" powers a role or job, while everyone else is left to be dead weight, who's main role is to inflate the number of mutants and have the chance to produce more "valuable" children. A situation only sustained by the artifical creation of all goods and resources required thanks, to the magic wonder island and it's techno-organic technology that Hickman snapped into existence.
However if the "no clone/duplicate" situation would be relaxed, there is the realistic chance of the leadership deciding that when a crisis or situation calls for more mutants of a specific powerset than the current society can provide, to "make more mutants" who have these powers.
Which means either artificaly altering mutants with powers close to it, radically altering those who are "revived" via the cloning process of the Five or most likely clone fitting mutants quickly.
Meanwhile in the case of any clone, there will be the can of worms on how much a clone needs to be different from the original to actualy still count as duplicate or when they are a full blown individual aswell just sharing the same body as someone else?
Because in theory, the moment two duplicates start to live their own lifes, they stop being "identitical" and become individuals, because any change, starting from going left while the other goes right, alters their memories and experiences, which in turn starts the process of becomming different from another.
This is also theoreticaly how a clone gains a "soul" on their own, because even if they start without one, any feeling they experience and any experience they gain for themself, it should form a new souls unique to them. Therefor the idea that Maddlyn has no soul because she is just a clone, is also nonesense in the face of what various other "clones" clearly having gained souls in the fictional rules of the Marvel Universe. Unless she was somehow specifically designed not to have, which doesn't sound like something Mister Sinister would even bother to percieve.
The only way for duplicates to remain the same is if they are just multiple bodies forming one mind (and soul) and as we could see with the Stepfords even that process is not always resulting in pure duplicates.
Overall, this is just another flaw in the whole ressuection protocol, or at least the cavalier attitude that Xavier and the mutants have displayed towards it since it's creation. It's an unproven technology, they allready take for granted and caused them to develop the dellusion of being immortal.
Also while the "no clone/duplicate" rule is relative sensible as mentioned above, it also mostly seem to exist just to avoid the "awkward" situation with Madeyln being brought back and angering Mister Sinister, who is so important for the whole process that they made themself utterly depending on him.
