TLJ damaged things up in universe in addition to insulting us out of universe, we don't know how much damage this show will do to the universe and we're out of beloved classic characters to ruin, the closest we have left is Mon Mothma, but that's almost exclusively due to the character work Disney themselves did with Andor(still not sure how it was allowed to get through the cracks without turning into high action sludge) and I'm sure they'll screw up season 2 regardless.

Oh shit, one more thing I thought of. In Mando season 1 they basically made everybody able to be tracked from anywhere in the galaxy by their genetics by introducing these magic tracking beacons that all bounty hunters seem to have so that's some more damage disney did that I'd consider large scale
