Because apps on Quest are universally games, and those pretty much never use standard controls. They don't even all use the same engine, so Meta would have to provide a UE SDK, a Unity SDK, etc.

I never felt this was remotely an issue with the Quest, and more than it is with desktop games.

It's annoying as hell for applications like Immersed and for media players. If every app had a different way to position windows and the UI was good in 50% of them it would be one thing but every app I've seen with floating windows is terribly awkward, although anybody can think up a number of alternatives that ought to work better.
