Nevermind, I looked a bit closer and we are still using these shaders in a specific configuration where web content is rasterized in software with SWGL and composited via the old D3D11 compositor code.

So removing this script is independent from WebRender's usage of D3D11, it's the SWGL + D3D11 compositor configuration that would need to change.
