This isn't really something the logging library can do. If the language provides a string interpolation mechanism then that mechanism is what the programmers will reach for first. And the library cannot know that interpolation happened because the language creates the final string before passing it in.
If you want the builtin interpolation to become a noop in the face runtime log disabling then the logging library has to be a builtin too.
