The 16-villager cycling queue from New Leaf. Sure, it made for a nice little reunion when you saw a villager at Main Street or in one of the stores, but having to relentlessly churn through nearly two entire towns worth of roster for the sake of one villager is tedious. Though I personally never did it, I can't imagine anyone ever enjoyed doing that

Especially considering that in NH there's the starting houses which isn't to everyone's taste.
Imagine having the 16-villager cycle in NH. Send out a starter and want them back with their original house anytime soon?
Have fun with that!
If anything relating to previous villagers ever returned, I'd be down for something akin to what ACGC did. Occasionally you'd see a former villager strolling around the map and when you talked to them, they'd say something along the lines of missing the town and even remembered how long it had been since they left.
Of course, they could just end up in Nook's, Ables, or the Museum, but as long as it's not tied to a move-in queue again.
