My number one request is still: "please rewrite this legal answer in simple language with short sentences." For this, it is amazing (as long as I proofread the result). For actual answers, eh...
Legal language is what it is in large part because simple short sentences are too imprecise to express the detail needed.
Simple vocabularies, while attractive will inevitably fail to properly describe systems of any sufficient complexity without long chains of hard to follow low-level logic.
Any system of sufficient complexity necessitates the use of more complex vocabulary to capture all the nuances of the system. See: Legalese, medical jargon, chemical naming schemes, the existence of mathematics itself, etc..
