I think this is a completely terrible idea. I'm personally on extended leave from playing Aurora until the NBT arrives, and even then I would not expect to massively dedicate my time playing on Aurora because my motivation for joining a round largely depends on the players connected to the server. If I see names I recognize, I'd be inclined to join, if I don't, I will most likely not, because there is definitely that impression people won't take you seriously if they don't recognize your character, etc etc.
But likewise, stripping whitelists for something inoffensive as choosing not to play the game is itself, well, offensive. It actually gives me and likely other potential returning players more reason to not return if we're otherwise unable to play the same characters in their respective roles again, because job-hopping is not tolerated here, and playing visitor can be horrifically boring in a roster of job-focused characters. This decision would be extremely isolating and would work against the idea of getting any returning former regulars back.
I would simply not return to play here if this decision was made. And while anyone is entitled to think, "Well, good" to however many exceptional cases that involve specific players, this decision would still end up coming off as intensely elitist and catering only to the in-group of current regulars' desires for quality control at the direct cost of risking that returning players will not be playing a majority of their characters on server, if at all.
I'd argue it's the command whitelist's team to account for returning players playing command and doing a terrible job of it to then moderate those players if they screw up, and escalate especially so on account of the typical, "Hey, did you read the rules, or did you literally just return to ruin rounds and chucklefuck?" -- in which case that's very open and shut, and it's fair, because it's case-by-case basis, and no one is to blame but that player. The idea in the title isn't fair and isn't open-and-shut. There are many awesome people who, while rusty if they returned, would still be amazing leaders, if not better after spending time outside this game to learn new life lessons. This idea really doesn't save you a lot more trouble than you think it would. Terrible command players, once they lose their whitelist, are unlikely to get it back barring an incredibly unique circumstance. But it's your job as volunteers to moderate and deal with that when it arises on a case-by-case basis, right?
And in any case, even if a particular person who was whitelisted applies, and their app quality is fine and their behavior is fine, they would still be screwed if the whitelist team suddenly decides, "Actually, we're not going to re-whitelist you." And their whitelist removal isn't even for something punishable, you just arbitrarily decided they would be de-whitelisted for inactivity (not against the server rules nor is it a thing not mentioned in the rules that could be considered against the spirit of the rules, so therefore it's ridiculous) and that you would not re-whitelist them because you don't feel like they should be. The decision is already arbitrary, so it doesn't matter if you just said "I would not strip them for any arbitrary reason", because this is an already arbitrary decision. QED, this is bad.
That being said, the staff can do what they want with their server - fairness and honor are social constructs - but it strikes me as odd that the command whitelist team even considers this idea while saying that bringing back the old regulars with the promise of a different experience is important. The potential action that would isolate a lot of people from playing doesn't match up with the words promoting inclusivity. Tell me to cope if I'm getting the wrong idea here but the hypocrisy just sticks out like a sore thumb. If you value quality control more than the quantity of returning players than just say that and do the quality control thing, forget democracy.
