Sure, but it leaves anyone just seeing an unattached `String fileName` to wonder which of the two it is. I.e. the same type of issue we had with floating `java.io.File` instances bleeds out to the `java.lang.Strings`. Obviously, the latter is much more difficult. Maybe I just haven't properly internalized the fact that `FsFile` is always `/` as you have, but if I look at the `toString()` call and am unsure, then likely others will be as well. There may not be a good solution.
