The list of participants is considered private. Under the rules of participation up to this point I am not allowed to tell you who is on the mailinglist. Individual participants are free to announce their participation, but they are not allowed to rebroadcast any of the private discussion.
I cannot even quote any individual from the private discussions in an outside communication channel. And without the ability to quote individuals it is exceedingly hard to make the argument as to who is leading or even supporting this initiative. I caution you to not make assumptions that are not supported by the public record on the matter.
Until the final documents are made available and individuals and organizations have the ability to publicly comment on whether or not they support the final documents, do not assume that any particular organization is going to champion use of these documents.
