This is arguably similar to VMware Tools’ DirectX support, where it works best on a Windows host due to being able to just forward DX calls to the host (with some partitioning/address translation). Microsoft’s DX backend for WSL could just be a wrapper around the host’s DX rather than a reimplementation. Making that work on any Linux machine would be impossible because it’s essentially just a shim.
