For consistency yes. But yet, I think I recall some functions that are not called with a compile-time constant, so we can't do that everywhere. Technically, calling a function that takes it as parameter from the templated version, and just passing our template argument is fine. What is not (easily) possible is normal parameter -> template. But again, that was just "for fun".
