I really wish we had a JSON 2 format which could fix JSON's obvious shortcomings. I would like to see:
- Support for Maps and Sets (unlike objects, maps allow arbitrary types to be used as keys)
- A standard Date format
- Embedded binary blobs. No idea how to do this and keep it human readable, but when you need this its super useful. Maybe something similar to WS's binary message encoding.
- Arbitrary precision integer support. This is particularly useful for cryptocurrencies and for interoperability with 64 bit integers in other languages. And bigints are coming to javascript - https://github.com/tc39/proposal-bigint

- Maybe even fix JSON's weird unicode encoding: http://timelessrepo.com/json-isnt-a-javascript-subset
Unfortunately it seems like nobody 'owns' JSON enough to give JSON 2.0 the political weight it would need for cross-language support.
