Didn't it? I thought games, at least, all did this by default since ever? I remember positional audio being a thing back when I was learning DirectX 3.
sure it works to some extent but it’s basically never marketed as anything like an immersive soundscape (for lack of a better term) or surround sound. like, i should be able to put on a simple pair of headphones and reliably get a surround experience for any content that supports it on pc or mobile. it’s probably patent encumbrance which is why we see a dolby plugin in the microsoft store and stereo headphones marketed as surround for a (often substantially) higher price with an included dongle to virtualize the audio
