I imagine in earlier drafts with Kira seeking Luke out, the lightsaber itself was the MacGuffin and had the same function as the map in BB-8. Which, in retrospect, makes a lot of sense.
Hear hear! An awful lot of the twisted-panties reaction to TLJ is a consequence of Abrams's reputation and the out-sized influence Lost had on culture - and it's not Abrams's fault at all. (I loved Lost, thought 1/3rd of the last season was sappy rubbish, but the vast, vast majority of the mysteries were explained, and OF COURSE a story is about what happens to the characters first and foremost).
I was guilty of this: I went into TFA expecting Rey to be a Skywalker, and I left the film irritated that he hadn't just out and out said it - this was because I figured that was the obvious direction to go, and because I thought that, if TFA followed ANH so closely, clearly they were setting up another family reveal.
Then, when I rewatched the film on blu-ray, removed from expectations, I came away thinking Rey - who's told by Maz that she knows the truth, that her family aren't coming back - was just a random, and that Luke, Leia, and Han wouldn't abandon any of their kids like that anyway. Sure enough, that's what Abrams and Kasdan intended, and that's what Rian Johnson thought too.
People seem trained to think everything needs explained, or else the story doesn't work. The lightsaber, the Knights of Ren - these aren't things that need explained for the story to work (there should be more in TFA about the Republic-First Order dynamic though). But in the post-Lost world of genre film, TV, and literature internet culture, every little odd detail or bit of world-building needs to be addressed lest they be a dropped ball or a plot hole.
