It certainly adds value if you don't want to implement a mechanisms to 
autoconfigure v6 DNS resolvers, or don't know which way to adapt to do so.

So, IMHO, it's clearly useful to state that as long as both PDP contexts 
are open, DNS lookups for v6 addresses work just fine.

I'm not sure whether any vendor or operator would like to go down that 
route, but it seems like a possible alternative.
