exa doesn't sort explicit arguments?

Putting this as a question because I don't know if it's intended, or if I'm missing something:

    > touch older newer
    > ls -t older newer
    newer  older
    > ls -tr older newer
    older  newer
    > exa -sold older newer
    older  newer
    > exa -snew older newer
    older  newer
    > exa -snew newer older
    newer  older

sorting the arguments is useful for scripting.
