I thought my point was clear - don't get involved parsing JSON; I agree with the OP, parsing JSON is a minefield. I went further by implying that it is also unnecessary when ease of reading isn't needed, and called out some alternatives. I think it's amusing that you mentioned protocol buffers - were you aware that when I mentioned flat buffers that they were built in relation to performance inefficiencies in the very protocol buffers that you mentioned?

We didn't just "hackathoned the biggest thing since sliced bread", btw, we took a real world example of exchanging a human readable format for a human-with-tools-readable one and saw a significant win. High-bandwidth also isn't as prevalent as you think, and yes, you're generally paying both performance wise and occasionally monetarily for the laziness you mentioned. But then, if you've known this for 40 years and don't know how to measure it, there's not much I can do for you in a comment.
