With IE?

How can using them with XBL be necessary for compatibility with IE 
considering that IE does not have XBL? Do those who use XBL with custom 
elements use something else in IE (HTC perhaps)?

XBL is not commonly used on the Web, so it does not look like a very 
strong legacy use case. Was it just one bug reporter alleging the need?

Actually, allowing custom stuff in head is a change from Firefox 1.0.x.

Opera and Safari (like Firefox 1.0.x) put custom elements in body.
