We are doing it now. See

My point is precisely that we will not be able to get the world to agree on
a single set of development tools, a single "language" for definition of VR
scenes, so we should at least come up with a way to integrate pieces that
people produce using disparate systems.

If a programmer can produce a better, that is more realistic, simulation of
a scene by coding it directly in GL than if (s)he had coded it using a
self-contained VRML script, then that programmer will use GL, not VRML.

It is presumptuous of us to think that we can dissect the problem of VR
scene description to create a level of abstraction that will be suitable for
all circumstances. We are undertaking to provide for the world a means by
which virtual reality simulations can be accessed and distributed through
the Web. Those means must be capable of creating not only flight
simulators, but also simulations of heart surgery.
