I think it allows for too much. I was glad that JSON only supports double-quoted strings. It is a feature that removes discussions about which quotes to use. Or even whether to use quotes at all (we still need them for keys with colons or minus in it, so what gives?).
The only thing that JSON is really missing are comments and trailing commas. I use JSONC for that. It's what VSC uses for the config format and it works.
