One thing slightly related to this change, but good to keep in mind, is that it seems like the overbuilding bonus card only seems to apply if you put in a building and don't re-adjust. Not sure if you have some production in if it keeps it, but I tried a couple times where I was like queueing up multiple buildings, if I swapped them around, I would see them go from like 5 turns to 7 turns, presumably because they lost that like 20% bonus to overbuilding.
But yeah, it's a weird thing to figure out if it's worth bringing your old cities forward as new ones in the new eras or not. Starting fresh is nice because you don't have the old clutter, but those old production buildings do help, for sure. It definitely encourages overbuilding, it's worth losing a few yields to get a building a turn sooner.
