Honestly I just wish they would drop the entire outwait humanity thing because it really screws with the metaphor and also approaches really bad ground with the entire great replacement nonsense going around. The idea that mutants, a metaphor for minorities is just waiting for all the majority to die out and be replaced by the minority, is unintentionally fulfilling a lot of very racist conspiracy theories used irl. I at least think they retconned the E-gene away which made that issue so much worse
