No. The removal of titles is only to keep the chain of command. You can't be duke and have an estate without being region lord as that means someone is both above you yet below you and makes no sense. Same thing with being a ruler in that you can't be a lord and ruler without being duke because your duke would be your vassal and boss, which again does not make sense.
Yes and no. I'm pretty sure that some government elections still kick out the incumbent. I may be wrong, as it might have changed, but I remember having to rerun for some of my lordship titles after winning a ruler election. That was likely before the new system, though, but I was under the impression that most of what I've witnessed since was due to this code, and not the oath auto-"fix" that runs two hours after TC.
