IIRC some of the Batik examples show 3D rendering within any SVG Viewer. 
They are simple exaples but show quite clearly what can be done.

It has been extended. Yes, it's trivial to do for simple things, and 
might get harder if we're talking about complex 3D shapes. Thus far I've 
seen little demand for elaborate 3D in SVG, and given that there are 
other existing efforts such as X3D I don't see a good reason for adding 
those features to SVG. As it stands, it is imho almost feature complete. 
The rest just needs a slightly better extensibility framework.

"remains" sounds a touch condescending to me. It is 2D, that's what it 
set out to be, and it does it very well. Given the complexity of moving 
from 2D to sufficiently elaborate 3D, and that the better part of what 
one does on a terminal is 2D, I think it hits the 80/20 mark far better 
by sticking to 2D.

For cases where 3D may be desirable, it is very much possible to have an 
SVG implementation interact with an implementation of a 3D vocabulary. 
The SVG plugin used in Real One as a SMIL enabled component show that 
rather well imho.
