In-depth EU stuff like ship deck plans and such, that seems to be more old school LFL and new (IE: Disney) school LFL doesn't delve so much into everyone in the background and their ships and whatnot. Of course the movie's not that old, and all the licensees move right onto the next thing and stuff, just like the toy line and stuff. No moss growing under anyone. So something more detailed is possible, but right now there's so little on any of the new film's characters, vehicles, etc. It's really a huge difference between now and the prequals in that regard.
Assuming someday Star Wars slows down again, I can see them going back through many things and taking a microscope to this or that.
