some writers do explore as much of the history as they can. Kurt busiek when he was writing carol's addiction story weaved it in pretty well, but he would explicitly a page or two to it.
Brian reed made isolated arcs where she dealt with the brood and mar-vell and what he meant to her. Deconnick brought back the wishing well aspect to the magnitron and told it through a time travel story
Like my thing is if you write stories related to her evolution you don't have to bring it in.
Carol was the perfect combination of rickjones, mar-vell and the negabands in one person, yeah, but the specific mechanics of how that works can be elaborated on to show why she was different. It can also be further tied to her themes of identity, perseverance, reaching for her potential, passions of space etc
