Yeah I don't see any problem with individual meetings making a statement such as this. I can see why it has not been accepted by the GSO though, there is no message of recovery there, and it has nothing at all to do with AA as a program.
As far as 13th stepping... I don't get it, people get all up in arms about "Ohhh (s)he only has however much time, (s)he shouldn't be talking to them...." I've never understood this putting an arbitrary time stamp on new people, like after a year they are magically functional, after a year god suddenly removes the obsession? I had always been taught that I am only a newcomer until I've done the work and had a spiritual awakening. Sometimes this may occur in a week, sometimes in a year.
Also, why is the assumption that there is always distinct "victim" in these situations? Does this behavior not speak volumes to the state of both parties, that both are so desperate for a distraction, both more than willing to wrongly place their reliance upon another human that they mutually make the decision to do whatever feels good at the moment. Just because one hasn't had a drink for a while does not mean that they are healthy. And, to that end, the book is pretty clear on how to handle such people-as any other sick person.
In my experience, at least with the dudes, I pull them aside and pose this that type of question to them, especially if I notice that its a cyclic kinda behavior. Offer to help them do the work, again if necessary. Beyond that, its not my job to make sure these people are "safe". Its simply my job to carry a message to them, and yes, part of that message is that you cannot transmit something you haven't got, soooo if you haven't got it.... then stay away from the ladies.
