The main feature this would lose is drag and drop of vCard and vEvent 
metadata from (unscripted, static) HTML pages to non-Web applications like 
Address Book.app or native calendar applications that support iCalendar 

Do we want to drop support for dragging contact information from the Web 
to native apps just so that we can change which spec holds what? That 
seems weird. (We could split the sections out and have bidirectional 
normative references instead, but that seems to defeat the point of 
extracting the sections.)
