Does anybody knows the development progress of uinty3d on SDL backend?

Hello, I am a newbie in Unity3d and I want to run Unity3d games or programs on Wayland, not Xwayland because our company are making Linux platform fully based on Wayland.

I found some articles related to this:

• https://www.gamingonlinux.com/articles/unity3d-working-on-sdl-and-wayland-support.7201

• https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/wayland-display-server/871067-unity-developer-is-working-on-sdl-port-to-allow-mir-wayland-support

But it seems to be not official and one developer made it by herself. Does anybody knows any progress after this? or Does Unity3d have a plan to support SDL backend offcially?
