I considered that approach, but an extension makes it possible to have
a conformance test that verifies that the WebGL context returns the
correct values during a lost context and correctly invalidates old
resources after the context is restored.  You can't test the WebGL
implementation itself with a pure Javascript implementation.

It's just a bonus that app developers could also use this extension
for their own testing without having to write their own (hopefully
correct) version.
