The problems start when people _maliciously_ modify the inside of your 
widget.  Again, with XBL you don't get to accidentally modify the

of attack scenarious where people could modify them at all.

I would like to understand more here.  How does preventing touching the 
shadow tree by default prevent something like Google Feedback?
