Darius, that's only partially true. Per policy, CG cannot publish normative specifications. It's NOT true that "only a WG can". S6.2.6 explicitly describes how AP can be updated without a WG. It requires W3C staff help, and requires backwards compatibility. Clarifying and improving the spec has always been possible without a WG, but not if W3C staff obstructs it, and not when insiders are determined to publish breaking changes despite lack of consensus.
