I personally don't give a crap about what is and isn't canon. For example, the Sherlock Holmes stories are not exactly canonical, yet it makes no difference to my enjoyment of them.
And as for Star Wars, I for example love the Thrawn Trilogy but if Ep7 doesn't take it as canon, it's not going to do anything to my enjoyment of those books and, if it's any good, of the movie either.
