The move definitely puts Rambeau right in the footsteps of the legendary Peggy Carter, and while the details only exist as exposition for now in the franchise, it’s certainly possible that we will get a first-hand look at her big story someday (similar to how the Agent Carter series put its titular heroine front and center in the mid-20th century).
As directly referenced by Jac Schaeffer, it’s now been made officially canon that S.W.O.R.D. in the Marvel Cinematic Universe was created because of the efforts of Maria Rambeau, memorably brought to life by Lashana Lynch in 2019’s Captain Marvel, and one of the coolest things about that is how it continues a tradition of awesome women in the franchise building massively important organizations.
