> Building an attachment point into the tag

To be fair, most people I know put their AirTag inside something, e.g. inner pocket of a bag.

At which point the necessity for an attachment point becomes somewhat moot.

It's useful to have an exterior one for a keyring (which credit card sized versions don't work for).

Same. I've never seen anyone put an AirTag on a keyring.

Oh, wait...
