iOS ecosystem generally doesn't work like that. Most people upgrade to latest when latest.1 comes out so around December. Those on latest - 1 will remain until they become latest - 2 next September and by then, they will very likely upgrade to latest because they buy a new phone. See this blog article by Telmetry Deck about iOS 17 adoption: https://telemetrydeck.com/blog/ios-market-share-13-23/ https://telemetrydeck.com/blog/ios-market-share-13-23/ Since Apple controls phone updates and phone support is long, unlike Android, most companies only do latest - 1 except around September when they will do latest - 2. However, most don't cut people off, you are just unsupported land and they will if older iOS versions give them any trouble.
