Basically, all OGF is asking for right now is, that instead of
forking, a new name or version number is applied to a specification,
so that a specific OGF recommendation can still carry that interop
promise.

A trademark will do a better job of doing that than copyrights ever would have anyway.

@Gary: A standard is described by a specification - indeed one standard could be described by many specifications (for example, one official specification and one reverse engineered from a compliant implementation). Ideally you want your standard to be well described in specifications (supported by test suites, interop bake-offs, etc.) such that the implementations are interoperable.
