This is whining that people won't endorse a lazy, poorly scaling approach to an engineering problem... and justifying that approach by conjuring hypothetical whiners against a common, better scaling solution.

If you need 12 levels of nesting, add indirection, or live with the fact no one is designing formats to enable your oddball mess of a use case.

12 levels of nested braces in a single function is already a crappy idea: it's an even more crappy idea in a config file because of the generally inferior tooling, and now there's a downstream component that needs to change to support a cleanup (meaning it almost never gets fixed and the format just gets worse over time)
