If you start down that path you open up for a massive amount of changes. In order to to this, you have to properly 
authenticate every OPTIONs so that you can find out the configuration and answer that peer/user correctly.

Adding different answers for different OPTION target URIs may be dangerous from a security perspective. I don't think reacting to XMPP: uri's is especially dangerous, but before following up on this, we have to judge how far we want to go.
