I can relate. But after using JSON for a while (in files that I edit by hand), I found that I really want comments and trailing commas (which leads to https://nigeltao.github.io/blog/2021/json-with-commas-commen...). Next I'd probably want multiline strings (leading to https://github.com/json5/json5).

But if you use those extensions, all your tooling breaks.

(Aside: I think the real bike-shedding would start when you want to add some syntax for raw string literals, e.g. heredocs; it's one of those features that feels redundant, until the day when you really need it and you can't bear the pain of repeatedly escaping and unescaping.)
