YAML: It is a light-weight, human-readable data-representation language. It is primarily designed to make the format easy to read while including complex features. Since YAML is a superset of JSON, it can parse JSON with a YAML parser.The extensions in YAML are .yaml or .yml. YAML specifications allow user-defined data types as well as explicit data typing.

YAML	JSON
Comments are denoted with a hash/number sign.	Comments are not allowed.
Hierarchy is denoted by using double space characters. Tab characters are not allowed.	Objects and Arrays are denoted in braces and brackets.
String quotes are optional but it supports single and double quotes.	Strings must be in double quotes.
Root node can be any of the valid data types.	Root node must either be an array or an object.

I don't think this is something that needs to be in the core, nor something the core needs. So, an addon? It can be an addon. Somebody already did the addon: https://github.com/Beliaar/godot-yaml-asset Granted that it would need to be reworded for Godot 4. Does that work for you?

There's a proposal tracking this: #941

However, as noted by @theraot, this is unlikely to be added in core. The built-in ConfigFile class already does a good job of reading and writing human-readable (and human-writable) configuration files. Only use JSON when you need its interoperability 🙂
