This change was made in Catalina. They made it clear that iTunes is going away. iTunes for Windows will also be going away shortly. Apple doesn't support legacy software for very long. Then again, Windows 11 isn't terribly great in this regard either.This is what pops up if either my phone or ipad are plugged into the computer. It would appear that Apple just killed iTunes completely for syncing.
You should still be able to connect to Apple services using older clients, but those will require the latest security updates. IIRC, the only hardware that is no longer supported at all is the OG Apple TV.
