It already works with Instapaper too, I just explain it as a Pocket to Kindle service because that's what people use the most these days.
Personally I use Instapaper more for reading because of all the premium features being free and keep Pocket in sync using IFTTT for their good recommendations.
The number of times Pocket just either redirects to the original article, or drops salient bits of text (in particular, unordered list items) is really annoying.
