I mean, in Disney all forms of media are on equal footing in terms of canonicity. So novels, comics, games, TV shows, films, etc... They all hold the same level of authority. You mentioned the Ahsoka novel: yes, much of it was retconned years later by TCW S07 -- but that doesn't mean it wasn't "true" canon to begin with. Continuity is fluid, and is subject to change at any time, depending on the whims of the alleged "Story Group".
Anymore I just look at SW like I look at Marvel/DC comics: everything is canon until it is overtly contracted/retconned by more recent material(ie. the most recent information = the most canon information.) So for example, if a comic were released tomorrow stating that Superman has never actually been vulnerable to Kryptonite, and he's just been faking it all these years for the lulz... Then that would become the new "true" canon within DC.
Likewise, if a novel were published next month explaining that Dooku's entire fight with Yaddle wasn't actually real, and was just an illusion that Palpatine placed in his mind to test him or w/e... Then that would become the new "true" canon within SW.
IOW, everything is canon... Until it's not. /shrug
