I've actually never used this Windows feature, but in MacOS you've been able to drag a document to an application icon in the dock to open it as long as I can remember. Windows seems to be slowly succumbing to touch-screen-itis, where the interface is designed for touching first. Dragging on a touch screen can be kind of janky at the best of times so I'm not surprised they didn't bother making this interaction work in Windows 11.
