Hal, it’s up to you, ultimately. But I don’t think the EU should be a factor. If we use bbghost’s edit, and cut it to “Babu works for the crew. That’s not you.” It wouldn’t contradict anything that might come up in the EU down the line. BUT, it would help avoid what feels like a disjointed ret-con from the other two films regarding Poe’s backstory.

In other words, it would make the Hal9000 Sequel Trilogy more cohesive unto itself; while simultaneously avoiding closing off any doors to the EU. And actually, it would work even better with EU material that came out before TROS, which said he was raised in a well-to-do environment. Making him a Spice Runner actually restricts the EU much more.

If you leave it ambiguous, it’s the best of both worlds, really. Both sides of the issue are appeased.

That’s just my opinion.
