So I just had a thought of Speculation based on remembering Bloodlines. (Spoilers from Bloodlines follow, naturally)
Leia (And Luke’s) Parentage creates a bit of a scandal, one that effectively forces Leia out of politics. During this time, there’s speculation from the Senate as to what Luke’s going to do when/if he returns to the political forefront (Mostly in fear that in his recluse he becomes like Vader).
I wonder if this drama has blown over by now, or if it’ll have an impact on Luke’s ability to be involved in the future. I could see the First Order making great Propaganda out of it, at the very least.
