Hadn't heard of JSONC, but I've always been a proponent of JSON5 for this reason.

Agree. JSON definitely needs an update so we can get better ergonomics built in.
In code you control you can choose to use JSON5: https://json5.org/

CONL: "Markdown" for your config files
https://json5.org/
> The first version of CONL used # as a comment token, but I quickly ran into issues. URLs contain #, so my next version...
Every other language has figured this one out as well. Wrap strings in quotation marks.
> That led to a data-model where each value is one of scalar|list|map (Compared to JSON’s null|bool|number|string|object|array, this felt good).
I'm not sure what a "scalar" is in CONL (is it always a string?) but having fewer types than JSON is not a positive feature for a config file format. Even JSON's hand-wavy "number" type is problematic and TOML got it right to distinguish integers from floats.

If you want JSON with comments (and a couple other extras), use JSON 5 instead. (It's effectively the JSON++/JSON-C you mention.)
