Until someone cannot tell the difference between tab and space when configuring or you miss one indentation. Seriously, whoever thinks indentation should have semantic meaning for computers should burn in hell. Indentation is for us, humans, not computers. You can write a JSON with or without indentation if you want. Also, use JSON5 to have comments and other good stuff for a config file.

It’s entirely disingenuous because who the hell is throwing JSON into YAML without converting it? Oh wow, I changed the file extension and it still works. I’m so glad we changed to YAML!

Yaml is cancer.

Yaml is just arcane bullshit to actually write as a human. Nor is it intuitively clear how yaml serializes.
