I think that a decision to rub out the existence of Mara Jade, Jacen, Jaina, Anakin Solo and Ben Skywalker would be a giant middle-finger to the Star Wars fan community.
Making a movie that is based on stories millions and millions and millions of people have never read could be seen as a 'giant middle-finger' to the lovers of Star Wars moives.
OR we could just say it's a creative choice to try and make the best movie, and accept that nothing will please everyone.
