The original idea with a variadic-templates printf() was that it could replace the C printf by providing a superset of the C printf behavior under the same interface. Basically, it means that existing uses of printf(), when compiled with the new variadic-templates--- based printf, would get run-time checking of the format specifier "for free."
I don't know if that's particularly useful or not. At the time, it was more like a flagship "hey, look what variadic templates can do!" idea.
Now variadic-templates together with overloading may rescue variadic functions from lacking of type safety. There may be some other areas waiting to be exploited.
I don't believe this is being discussed. It's too late for such a change to get into C++0x, so the right answer is probably to revisit Boost.Format to determine whether we can now do something better.
It's a misfortune to miss the train to C++0x, but it'll be a grief if something immature gets into the standard. So let Boost.Format evolve :)
