I agree and I hesitated to question the fields usefulness but then brought
it up anyway since there is also value in simplifying the spec if the cost
in performance is essentially negligible.

Scenejs.org is a bit similar to x3d and has a json scene description. It
does not deal with triangulation of polygons.
Osgjs.org is a javascript implementation of openscenegraph. Searching for
convex on github only finds a polytope object which is convex by definition.
