MSVC doesn't do strings-vs-argument-list checking for printf-like routines, as far as I know; that's something we leave to GCC and clang.  If we add additional format string modifiers, we'd want them to be checked at compile time if at all possible.  ("Never put off until run time what you can do at compile time." - especially if it's checking; a compiler error presented to the developer is better than a run-time error presented to the user, no matter how good the run-time error.)
