But they need to be marked as non-normative. It would also be helpful to have an implementation table for vendor extensions.

What do you mean by normative here? The only distinction I see is
whether the extension is expected to be implemented only by a single
vendor or multiple vendors. It is perfectly legal for a WebGL
implementation to not support any extension, even one with a WEBGL_
prefix. If that isn't clear then I should probably update the foreword
in the extension registry.
