Or you can do what was suggested in the list (don't know if it is  
mentioned in the spec): cache the information about {client_name,  
client_version} => caps* only after you receive the exact same  
information from 5 or 6 different JIDs.

The roster is assumed to be for people you trust.

I think the case for service bots is the only one where I would limit  
the use of XEP-0115 given that by default a lot of JIDs will  
subscribe it and you'll auto-accept them all, so no trust there.
