Disney committed a Red Wedding on the both the PT and OT and the characters with their trilogy.
I am not sure all that wont eventually get retconned, at least partially. Its hard to say tho; right now they do seem to be doubling down.
Its one reason that we might have to sort of let go of those OT people and focus on something new for a while, to give the bad taste of all that time to die down.
SW is sad. I think of Aphra and all the stuff she does - lots of it is pretty damn bad - and her foreknowledge that "people like me dont get happy endings." She knows! She states this repeatedly. And she is trying to outrun it anyways.
Then Darth Vader airlocks her.
