Yep, the extension registry also says that "Every extension should advance to Khronos ratified". It would be good to add a separate track for non-standard extensions that are not meant to be exposed to the public web if some vendor is interested in implementing such extensions. But I'd defer adding such a track until there's an actual use case for it.
That doesn't address the issue I see. Without a way for a vendor to expose nonstandard extensions to the public, they're required to submit it to proposal, get it to draft and push it trough to community approved before they can expose it to the public. In turn this means that any single vendor can demand that their extension is elevated practically straight to community approved without consensus at the proposal stage, without alternative implementations at the draft stage and without community approval at the community approved stage.
Effectively your suggestion amounts to that proposal, draft and community approved are "standards exempt". I do think that proposal, draft and community approved are standards track states.

I think the WebGL extension registry should document all extensions,
even those which might not be intended for a standards track. It's not
a burden to write a little documentation for new extensions, and gives
other implementers the opportunity to provide some compatibility. It's
also not a big burden to leave an extension in draft status for some
time while its utility is being proven.
There was a long discussion about vendor prefixes for WebGL extensions
some time ago, with the conclusion that draft extensions should
preferably be exposed behind some sort of run-time flag, not enabled
by default, and also not use vendor prefixes. I've updated the
extension registry in https://github.com/KhronosGroup/WebGL/pull/861
to indicate this.
