I was going to ask the exact same question. The title makes it sound like something I might be interested in, then I visited the page and I have no idea what it does. After some brief reading of docs, I'm trying to write one sentence explanations.

Preserves forces you to deal with these vagaries up front What else? With P-Expressions you can search a preserve compliant datasource much like you would query JSON with JQ Who Not?
