We've never had permissions named this way... ?

You mean it's not the right style? Given r134463, we don't expect anyone to
actually include it in their manifest, so it'f for internal use only. It might
actually be nice to enforce that it can't be specified in a manifest.

No I just meant it stuck out that we haven't done this before. Sorry, it was
more a note to myself that I should have removed pre-publish.
I think maybe you meant a different rev? crrev.com/134463 seems unrelated.
