Meh, I consider myself pretty deep in my domains of expertise and even I regularly struggle because I haven't had that much exposition to a specific subject that is not exactly my specialty. You really can't rate these things unless you are literally among the top experts at the forefront of the topic. That's also who I'd have in mind when writing such a paper. Not some well versed enthusiast, not even a PhD student. Depending on your field, you might be able to count the people who can comfortably read and understand your paper on one hand. For everyone else, the effort will rise exponentially for every step they are removed from that specific topic.
