AV1 support was added to DXVA (Microsofts hardware acceleration API) in the Windows 10 2004 SDK update, hence where those come from. But no indication of hardware that uses them quite yet.
The other typical structures to convey codec information to the hardware are still suspiciously absent however, so it may not be fully finalized.
