How do we get X3Dv4’s VRML Loader put onto THREE’s task list?

I was referring to the VRMLLoader in Three.js. I don’t put a version on it, so if one rebuilds X3DJSONLD, one should get the most recent version of Three.js.
Don doesn’t mention a VRMLLoader at all.
I agree that support for X3D XML and X3D JSON is limited in the version I forked.
I hope that clears things up.
I think we would be better suited to port X3DOM or X_ITE to Three.js, but that’s a lot of work too.
Do we need a second VRML loader which meets the X3Dv4 standard? This might be where we could put in effort effectively.
What’s the task here? I don’t thing that the three-x3d-loader Don found (again) suitably matches the XML or JSON X3D standards. It’s more like someone’s experiment rather than a comprehensive effort.

John mentions an older, primitive x3d/vrml-loader. It is different
from the one Don found which is also very primitive.
Looking at github, Don's supports Transform, geometry primitives and
IFS, color appearance and Imagetexture. That's about it.
It still could be useful.
