None of my test cases made use of the return value. I think this means that I need to only match on calls that don't make use of the return value. I shall try to do that.

You can provide warning, but without fix. But that would need to be put into documentation.
If we lucky, and there will be no issues with current version, then you can put this in separate patch.
Anyway I do not think that many project use `printf`, most probably they use `std::cout`, `fmt::format` or some other custom wrapper around something.
