Good to know that they are at least planning to go in that direction!

I guess so. Some spec somewhere will probably need to state that an <X3D> 
element introduces a rectangular surface and then should describe how to 
determine its 2D intrinsic dimensions and/or intrinsic aspect ratio.

The next step, I guess, is to see if any Web browser vendors want to 
implement X3D! Is the X3D spec stable?

(Note that in the above the selector is wrong and the <div> is probably 
not the right element, but that's another story.)

No, there are needs for both declarative 3D and for direct-mode 3D.
