So I can't find it, but Hickman allegedly said in an interview years ago that Cyke was his favorite X-Man.
Also this was interesting from 2015:
IGN: There's also Cyclops becoming the Phoenix, which is a pretty huge thing, even though it didn't work out too well for him in AvX when he became the Dark Phoenix and killed Professor X. But that he has a Phoenix egg and used its power in the first issue, that could be a whole event in itself, but it was just a beat in this story. What was your decision to have him use it in the X-Men's last-ditch effort?
Hickman: Well, there's a lot baked into it. Certainly the death of everything seems like a very predictable and important place for the Phoenix to show up, certainly when you're talking about Cyclops, who is -- it's more complicated than this, but if you distill it down to its essence, you're talking about a guy who, since Professor Xavier died, is absolutely obsessed with bringing about, I would argue, the homogenized vision of what Magneto and Charles Xavier, both sides of that coin, have always been.
So I think he's the perfect conduit. I think the Phoenix is a completely predictable and acceptable appearance, and there will be, obviously perhaps, more with that.
