I think it's probably ok because one doesn't aquire a presence  
subscription to the members of a muc room, and as such PEP isn't  
going to fire off the notifications. From the same section:
Also, note that this works only if the account owner has a presence  
subscription to the contact and the contact has a presence  
subscription to the account owner.
I'm willing to believe there are interactions we haven't thought of  
though and I guess we await implementations to find them.
