Have you personally tried other methods when having an overload of server traffic?
Do you have a link showing a real setup of a better method?
Of note, the module is a port from the nginx tuned by alibaba which is quite a credible source.
I have served over a billion pageviews/month, and cutting off requests at a certain load threshold with a custom error page to users is a good idea. Otherwise the users will just get a huge slowdown or a backlog of requests which will cause a prolonged server recovery.
Also as the author vozlt mentioned, you can use "average of request processing times" and custom http errors. Also, it is much easier to use than the methods you suggest.
