I think this is a valid point of view, but needs to be balanced by a need for perspicuity.  After all, you aren't really using Arrows.  It's just a coincidence that this function does what you want on a concrete implementation level.  When I was learning to use the HXT package for XML manipulation, I was happy to learn about its use of Arrows.  It really uses them.  I need to understand Arrows to use it.

To me, this kind of use reads like a bad pun.  :-)
