Which is kind of a misleading statement. The canon levels aren't strictly divided by movie/non-movie either; GL has sanctioned comics, novel tie-ins, radio plays, and so on which are considered G-canon over more remote C-canon, etc.
While most Star Wars fans are largely ignorant to the stratification and diversity found in EU, those that aren't find it jarring when it's written off without a word. There's stuff in EU that surpasses GL's work in the last 15 years, to be honest. But there's also stuff that is total rubbish, because of both the nature of many authors and creators and Lucas' ridiculously lax policing. So Disney's plan to take a chainsaw to it (rumored) is probably going to become a reality. I point out again that they retained Leland "Most fans only care about the movies" Chee who has probably wanted to do as much for the last ten years.
If this DOES happen, well, a fresh start isn't a bad idea. ST reboot is successful and doesn't have quite the same level of baggage as prime universal material would have, but George Lucas didn't handle the EU-situation the same as ST. And how that worked is anything not a tv-show/movie in ST is pretty much non-canon period, whereas GL has this ridiculous flexible caste system going on which makes things difficult to control and interpret. There's entire debates spiraling out of control about EU interpretation in this very forum, though it's cooled down considerably with the lack of new content and the upcoming movie in the works.
In my opinion, Disney could do EU justice by lifting the best ideas from it, and canning the worst. If they mulligan EU and then pretty much recreate the highlights and implement it into their original story, SW would benefit. If they just hack away EU entirely and go off in their own direction, they're relying entirely on their own novelty, and this could potentially blow up in their face.
