No it doesn't. The answer to needing a string manipulation function would be to use a string manipulation library that include that function, not one that is nothing but that finction.

If you don't need anything else, and having the linker not include unused code isn't good enough, then just vendor the single function.

There could still be some special case but that will need a lot of explaining to justify and will be such an exception that it is silly to talk about. There are legitimate one time freak exceptions to every principle. It means nothing.
