The Same Rule applies to Dr Who’s Relatively Scrambled Timeline as the TV series overwrites what the events of Audio Dramas all the time because it’s easier for the audience just watching the show on it’s own
Actually Who is a pretty different situation. Who's writers and showrunners specifically reject the idea of "canon" - there is no story group, you can believe in whatever you want, the show occasionally contradicts itself, and generally any conflicts can be explained away by the effects of time travel.
When Star Wars was acquired by Disney back in 2013, they rebooted the expanded universe, declaring all existing material as "Legends" and not canon. From then on, the policy was that all content, regardless of medium, was equally canon, and for the following few years were extremely successful at making books connect to comics connect to shows connect to films, with everything fitting together into one big story. It's a really interesting storytelling experiment and quite unlike any other franchise I can think of. Dr Who was actually inspired by this approach to create the Time Lord Victorious crossover event.
In any case, I for one have really enjoyed Star Wars' interconnected expanded universe - it's why I made this timeline - and hope they continue to support it. It's not just a case of "only films and shows are canon", it supports everything and is really rewarding for those of us who try to keep up with it. I can live with these occasional slips, there are only a few after all, and it's still way more consistent than anything else in pop culture right now!
