The most stalkable users are android users, but even that it's going away with newer androids. And it already beeps when you move it if it's been away from the owner for too long.
I know because I have an android phone and a not-so-used ipad and mine beep all the time.
What stalking scenario are you worried with?

Not sure about that. My Android warns me about my wife's airtags so often, that if I would actually be tracked by a malicious airtag, I would just assume it's one of my wife's tags. This could be prevented if I could mark a tag to be trusted on my Android phone, but no such feature exists.
