Agreed. They pulled apart the old shared universe, fyi, because there were too many narrative contradictions and too many story-mind contradictions. That is to say, the canon was messy without a story group deciding what sort of stories they wanted to tell and to make sure everyone was on the same page across the various publishing media.
More to the point, the canon was telling stories that were contradictory in their messaging. Star Wars can have depth of messaging, but it should sabotage its core themes with the ancillary material. There's a reason that Darth Bane and Darth Revan did not show up in the Mortis arc as Sith Force Ghosts; the very concept undermines the ideas of what the Dark Side is and the path to immortality. We see that in order to live forever, instead Palps has to drain the lives of others, or live on in degrading clone bodies, or transfer his consciousness to possess the body of another. He can't become a Force Ghost. Anakin became one ONLY because he was redeemed in the end.
Now, this has been a little nebulous in some spaces. George famously wanted no place for Jaxxon in the canon of Star Wars, but a green-furred rabbit-like humanoid alien species is not in and of itself a problem with Star Wars. And Jaxxon's silly antics seem to fit right in with Jar Jar Binks and C-3PO and their silliness. So the new canon has cautiously reintroduced him to the canon, to the point that he gets a relatively high profile story in this years The Empire Strikes Back From a Certain Point of View (previously he had only appeared in canon in the youth-oriented comic series Star Wars Adventures, and even then, only in special Annual issues).
There's room for a lot of what was Legends, and we can see it kind of like with Marvel's approach to Spider-Man - a lot of what you know from past films/comics/novels happened, just not necessarily in the same way or with the exact same details. The serial numbers are filed off. If it directly contradicts the new canon, it didn't happen (or the bits that contradict didn't happen, at least). But there's still value in the older stories, and Dave Filoni has delighted in reintroducing stories and characters from the old Legends. I wouldn't be surprised if Mara Jade was even a thing in Luke's life, only to have separated from him or died prior to his training of Ben et al as seen in The Rise of Kylo-Ren.
