It can always be added later in such a way to give it some kind of meaning, though I am not sure a typical headgear for her would work well with that outfit.
It does factor in some ways into how some writers depict her including Duggan. Its why outside of wishing we got to see her nightmare in issue #4 I haven't said much about it. Marvel doesn't like fans to badger them about things which is why I try not to even though it really does matter. Fans calling for stuff is why Duggan basically admitted on Twitter they kept Jean in her 05 costume for another year.Hopefully we'll get someone to touch on Genosha for Lorna at some point. I understand the frustration of not seeing it explicitly said, but I do feel it factors into the way certain writers depict Lorna's personality.
Bunn's run with Lorna is a picture-perfect example of a run that was horribly undermined by wanting to drag Lorna back to the 90s and ignore the later stuff.
That would be quite something though I don't believe they would ever do it. Lorna and Magneto’s relationship was deconstructed over the past two years and still are going to have to be rebuilt somehow.I do wish we could get a scene of Magneto and Polaris discussing their time on Genosha in more detail, particularly in this era of the X-Men with everyone united on Krakoa.
