These releases tend to be yearly or half-yearly at most (e.g. android or ubuntu). So a wrap around happens after 13 years at the earliest. Having a 13 year old completely un-upgraded phone (or AR brain worm or whatever we will have in 13 years) wrapping around seems quite unlikely to cause any surprise.

If you have weekly releases or something, then I would see your point.
