Posting this because I haven't seen high-level questions related to serialization format design discussed so clearly anywhere else.

JSON Schema existed in 2018, so if needed, JSON isn't fully schemaless.

JSON Schema doesn't prevent meta repetition and has no sense in the topic's context.

I'm not sure I understand what meta repetition is, but JSON Schema is a schema mechanism for JSON. _A_ schema mechanism. Maybe author meant something else, but, well, that's how it's called - and arguably it's a good name.

This JSON

    [ {"foo": 1.2, "bar": [1,2]},
      {"foo": 3.4, "bar": []},
      {"foo": 5.6, "bar": [10,11,12] ]

could be shortened to

    [ { foo: real, bar: [ int ] ]
    1.2 1 2; 3.4 ; 5.6 10 11 12;;

which is significantly shorter and also confers important performance and safety benefits.
