Click on this link to find out 'How to reset your AirTag' --> https://support.apple.com/HT212251
"An AirTag can be associated with one Apple ID. If you want to use an AirTag that someone else has used, they need to remove the AirTag from their Apple ID first. If the previous user removed the AirTag from their Apple ID but they were out of Bluetooth range of the AirTag, then you need to reset it before you can use it with your devices."
The people posting here are users like you and we do not know what Apple plans until they make a public announcement. You can send them feedback. I know this is a frequently asked question here.
