"Please put yourself in the shoes of someone actually operating a site." - I run 8 sites right now and one of them is processing 10,000,000,000+ requests a month. I speak from a position of experience on this topic.
"Every single issue mentioned in that post only affects end-users. Not a single issue for the operator" - so don't care about the user and the risks we expose them to, only ourselves? This isn't really an approach I'm happy taking.
