And also there are security concerns that the client needs to be doing 
the ignoring (or error messages) if the feature is turned off and not 
advertised to someone, i.e. a mallicious client could send an attension 
to you even if you arnt advertising support for it and you shouldnt just 
accept and process that request if the feature is turned off so its not 
like you can reduce any coding by not advertising it to people.
