You can extend jabber:iq:browse quite easily! If you do that it will get all the features 
required/mentioned in JEP-0030 and will also still continue to be compatible with all 
current implementations!
Also by doing this the jabber:iq:browse would not go to look hackish! (we do not have to 
fear that!)

This would mean much less work for us client coders... and older components will still 
work and if a JID does not support restrictions yet the user can do a normal browse 
request! 

It is much easier to extend my own ocde then to write a new one!


My SUGGESTION just add this to the JEP-0011:
add the restirction options to the jabber:iq:browse with #option
add some other level stuff like <ns/>
for example:
CLIENT
<iq to='component.jabber.org' type='get'>
	<item xmlns='jabber:iq:browse#info'/>
</iq>

COMPONENT
<iq from='component.jabber.org' type='result'>
	<item xmlns='jabber:iq:browse#info' type='jabber' name='something' 
jid='component.jabber.org'>
		(<ns>jabber:iq:register</ns>) <- removed by restriction!
		(<ns>jabber:iq:gateway</ns>) <- removed by restriction!
		<info blah='xyz'>Someinfo</info>
	</item>
</iq>
