1. Tying AR to a static point

Uses: Being able to physically walk around a life-sized 3d model of an engine, human body, etc.

2. Tying AR to a point relative to the user

Uses: Heads-up Display notifications, virtual screens, etc.

These things are not mutually exclusive.

Even once you've placed a "AR object" at some static absolute location, I'm sure you can scroll through the list of active processes similar at any time, and snap it back to your body.

As somebody who hates the sedentary aspect of software engineering, I messed around with a friend's Apple Vision Pro and fell in love with the spatial computing aspect. I do a great deal of pacing when working through problems, and the ability to physically move around multiple virtualized workspaces was really engaging.

I have Xreal glasses, and it's handy to be able to pin a window to a physical spot (well, direction in this case). I used that feature to have basically a virtual TV on my laundry room wall while I watched a video on how to fix my dryer as I was fixing it. But if I'm playing a game or watching other content, I don't want to have to focus on a single spot, so I have the window always in front of my face.
