AirTags and Family Sharing

Tim Hardwick, MacRumors:

On the face of it, sharing the location of an AirTag via Apple’s Family Sharing feature should be a no-brainer, since individual members in a Family Sharing group can use the Find My app to see the location of other family members’ Apple devices, including iPhones, iPads, Macs, AirPods, and Apple Watches.

Seems a fair point. I can find my wife’s iPhone or Mac, but not her AirTagged item.

Is this intentional, some privacy aspect that Apple is protecting here? Or is it early days still, with the AirTag team still building out the various tracking mechanisms?
