Even if things are "officially" canon, I feel like they are slowly moving away from certain core ideas and concepts by simply not mentioning and/or ignoring them and that gives you an idea of the direction they are going.
There are no Sith and Midiclorians in The Force Awakens for example. JJ even went out of his way to explain that Kylo Ren is not part of the Sith (and implies that Snoke is not either). I would be very happy if they completely wipe out the prequels and all the Force lore and started over because it has gotten too technical and entrenched in decades of clumsy material the general public doesn't know or care about.

They are moving back toward the cloaked mysticism of the first three films and that works wonderfully in my book. Ren and Snoke are force-sensitive that are simply powerful in the dark side of the force (and the dark side was all that was ever mentioned in the original trilogy). It was always more elegant to me that way and it didn't need to be elaborated on or being branded with a silly name or being codified into rules.
