Firefox:

    >JSON.stringify(1n)
    TypeError: BigInt value can't be serialized in JSON

Chrome:

    >JSON.stringify(1n)
    Uncaught TypeError: Do not know how to serialize a BigInt
    at JSON.stringify (<anonymous>)
    at <anonymous>:1:6

I don't think we're quite there yet.

It was counterpoint to "that does not mean that JSON itself or all implementations have the specific limits of javascript."

Javascript can do arbitrary precision integers now. So the last part is not true. You can generate your JSON strings with string concatenation in JS if you like.

Just because JSON.stringify has some limit doesn't mean JS has.

See my comment elsewhere in the thread that shows how to properly use BigInts with JSON.stringify, if you choose to support them in your environment.
