So basically what you're saying is, the only way to find out is to try and 
then get an error, because:

  1) a server might be 100% XMPP compliant, and simply allow the privacy list
     feature to be disabled, or;

  2) a server might not claim to be XMPP compliant at all, and still support
     the feature.

IMO, it would be useful if there were a way to find out if a feature exists 
before trying to use it (like we have for almost every other feature.)
