The cat is out of the bag. There is no way that people are going to stop putting AirTags in their luggage, at least not while airlines are still constantly losing luggage and fighting people on reimbursement.
Just wait until an airtag lithium battery catches fire in the cargo hold.
Enough of a mitigated safety risk that the CR2032 that the AirTag uses is small enough to be exempted from the lithium battery rules.
