Originally Airtags could not be shared with other people.
If I placed one in the car, it would bug the wife while she was driving.

Now I can share an Airtag with the wife and it won't bug her by telling her she is being tracked.
It also will allow her to track the Airtag.

Airlines originally tried to ban trackers in luggage.
I think they were embarrassed by customers telling the Airline the location of Luggage the Airline simply could not find.
Nothing states incompetence like "We are still looking for your bag" only to be told "it's still in Texas and has remained there for two days, while I'm in California"

Airlines are now setup so that a Airtag location can be shared with them by the owner & the Airline can see the bag location for themselves.
