I'd really like dhuzak and penelopy to have flavor text that establishes every polity mentioned in other, definitely current flavor text (of things that are still alive and in use like ships) that died with them.
Like, if Fabrique Orbitale used to be where the crater of a Great Crater world is because one of their Orbitales wasn't quite so Fabriqued, I'd love to be able to dig that up in survey text. Maybe even uncovering the final shipping logs of a ship manufactor that died as soon as the collapse happened you could get an unmarked quest that spawns a perfect condition s_class midline noncombat ship that's in a derelict convoy that never reached its destination being tended by a attache of drones that you could find if you fly from that planet to the nearest derelict ring, and then from all of the destination planets to their nearest derelict rings.
And then, if you take the ship without modifying it or letting it take damage ("new, showcase condition") to the destination planet a quest dialogue will come up mentioning that one of your crew muses that the convoy might have not been at it's final stop, and if you then go to the other destinations one of the other planets, if surveyed, contains a settlement of mercenaries squatting in the abandoned delivery site and the quest can be completed by you trying to turn over the ship to the mercenary quartermaster, whose salvaged pre-collapse computer confirms that this delivery is expected, doesn't check any of the dates on the paperwork and pays you for the now-worthless corporate luxury shuttle in it's pre-collapse value.
