Now as a die hard Star Wars lore buff, I'm constantly getting upset when decades of amazing lore gets largely ignored or brushed away by Lucasfilm. It got to the point that there had to be a sliding scale on what level of canon things are on. Some of the things in "George's canon” flat out spit in the face of things largely accepted and loved by millions of fans.
Yet there are times when that's really a good thing. It was nice seeing Selkath, the aquatic species from Mannan from Knights of the Old Republic make an appearance in the Clone Wars TV series, which is on the same level of canon as the films, as well as the force unleashed games.
