Not true, it's a file format. A new parser can easily be written
and an the internal format, once loaded, can be tuned easily. I have
written softImage parsers for Inventor and a Renderman translator for
Inventor as well.

yup it is. In the file format. Defining and reusing objects in
the file format is not hard at all. If we can come up with a way to
define new primitives using the Inventor syntax, we can add them to the
VRML specification. I don't think there is any plan to limit us to
Inventor. It's just a good starting off point.
