it could give Obi-Wan some background maybe, that is really missing - where the 'ell did he come from ?
that was one question I would have liked answered, not to see a baby-Vader making his first steps into a bigger galaxy ...
so should Qui-Gon and Ben be residents from Naboo/Alderaan or just "stationed" there for "peacekeeping" ?
they could start as friends with Bail Organa, to give later mentions credit
