This is undoubtedly cool but I'm curious to know of a use case that would warrant installing this. Could this just have been a step in creating "Windows Subsystem for Android" [0] that they decided to release as its own layer? The screenshot on the github page shows VSCode, Edge, Blender, Xcalc, Xclock and GNOME file manager which are all either available natively on windows or redundant. [0] https://www.xda-develope…
Pretty sure the point of the WSL and WSLg projects are to lure developers who would otherwise use macOS. After all, your local environment is likely even closer to production using WSL than it is on the BSD-derived macOS userland and Darwin kernel. Actually, early on in its life macOS (poorly) supported X11 apps using XQuartz as a similar lure.
