I'll go one further -

Forcing LLMs to output JSON is just silly. A lot of time and effort is being spent forcing models to output a format that is picky and that LLMs quite frankly just don't seem to like very much. A text based DSL with more restrictions on it would've been a far better choice.

Years ago I was able to trivially teach GPT 3.5 to reliably output an English like DSL with just a few in prompt examples. Meanwhile even today the latest models still have notes that they may occasionally ignore some parts of JSON schemas sent down.

Square peg, round hole, please stop hammering.
