"The reason to make it optional is that Direct3D 12 support currently relies on the proprietary dxil.dll library from the DirectX Shader Compiler being shipped together with Godot, and shipping proprietary software goes against the mission of the Godot project."

The license (and the code) for dxil.dll/libdxil.so isn't in that repo, they just include the blob in releases. If you look at a release you'll see an additional LICENSE-MS.txt that just covers that dxil signing library.
