I'm in favour of trying it out before freezing the feature.  That 
means going ahead now with an implementation, and reconsidering it 
in a few months.  Perhaps marking it experimental with an appropriate 
warning message.  A few months is little enough time to use it that it 
won't be traumatic if code that uses the new features has to be 
partially rewritten.
