Well, they learned the base’s location in the theatrical version of TFA, too, so that’s not in and of itself a Restructured change.
No, but people were talking about taking that line out because it leaves a bit of a dangling plot-thread, but leaving it in is relevant to TLJ at least - sorry, I was agreeing with you that leaving it in is fine, and that another justification for leaving it could be that it ties in to TLJ as well.
