I have a copy of 3.23.56 running on one of my machines and it does NOT wrap auto_increment columns when the upper limit is reached. I haven't tested it with any newer versions, though I doubt they'd be any different. If this is a concern for you then I would suggest using a bigger column type for auto_incrementing and making that column unsigned. The extra space required for your DB is really trivial compared to the saved headaches of devising your own wrap/reshuffle scheme.
