I completely disagree. A good full-stack dev knows SQL pretty well: at least well enough to be able to work through the general questions in the document. Good SQL skills are essential, and the lack of good SQL developers I would attribute mostly to ORMs that abstract it away so mediocre developers can mostly ignore it (which makes the job a whole lot harder for people that actually DO know how a relational database works, and give it the respect it deserves)
