Oh, right, I got ahead of time. :)

I think everything that needs to be tested, needs to be tested in Core. That 
includes legacy forwarding headers, if needed, although I wouldn't say that 
such a test is very useful.

Duplicating tests just adds confusion (and wastes resources, as you said). 
Even if we don't forget about them, which is possible, when the time comes 
it'll be more difficult to get rid of them. One would have to analyze both 
Core and Utility tests to see if anything needs to be pulled from Utility 
before removal. It's easier and safer to do everything once now, when the 
context is not lost.
