It’s a tag, that works well as a tag.
Also, you can use it as a remote shutter should you wish to place your phone somewhere and take the photo from somewhere else - like standing in front of a famous landmark, or wanting to be in a group photo instead of being behind the camera.
Seems like a no brainer bit of useful add-on functionality to supplement its primary usage.
I bought a car that has heated seats and a heated steering wheel that I’ve never used, and being in Australia will probably never use. It did not detract from the rest of the cars functionality including its main purpose which is to get me from A to B.
I suspect the optional functionality of this hardware button will be similar.
