The clear answer is probably appreciated however the implication that reimplementing something needs to be "justified" is absurd, even setting aside the fact that the syntax you use is representative of the arbitrary, inconsistent, and generally horrible CLI of unix commands, and does not represent a good case against implementing a better interface. Open source is packed to the brim with "reimplementations," some out of ignorance, some for learning, some to improve, some to port to different languages, some for ego, some for principal, and some for many other reasons. Frankly the code is hardly deserving of derision. It looks perfectly capable to me, and the syntax is far superior to arcane unix commands. Just because you'd rather write a sed wrapper than write this code doesn't mean it makes sense to deride others for trying to move the human race forward.
