As noted in the XEP, the server actually returns what it perceives to be the client's IP address.
What the security considerations miss is that doing so may unintentionally cause disclose information about the network information the server operates in.
Server operators likely don't want to enable this if their server sits behind a reverse NAT (or some sort of ALG/proxy) as it would disclose the inside IP address of that reverse NAT. Even if that isn't a security consider for the server operator, that IP address is likely not what the client wanted.
