Shadow support for KHR_lights_punctual ?

[kitaedesigns]

Wondering if GLTF Lights can support shadows in ThreeJS? The lights work perfectly but there's no shadows and I'm having a hard time finding any documentation surrounding this besides this post. https://github.com/takahirox/KHR_lights_shadows

That seems like an implementation-specific detail. glTF lights define lights with physical units, and so should be expected to behave like physical lights, including shadows. If an implementation omits shadows, that's a mistake in the implementation.
