Ubuntu Desktop Installer (UDI, for short) package implementing the WSL OOBE has been ported to Windows and the WSL application is able to launch the OOBE running as a native Win32 application, instead of relying on WSLg to display the OOBE.
That implies in the possibility of replacing UDI snap by Subiquity one, which results in a much smaller rootfs image (besides an enhanced experience due native rendering on graphics - instead of depending on RDP as it is currently with the OOBE running inside Ubuntu).
Updating this package to latest upstream allows launching Subiquity as a snap indepent of UDI existence in the rootfs. That approach above won't have effects outside of WSL.
Kinetic being not an LTS is a good release to receive the fix for this at first, as it affects a small audience of Ubuntu WSL community, giving us time to learn from them before backporting this to Jammy early next cycle.
