You could invent a language that represents data that is very explicit about having integers, the implementation in javascript would still spit out floating values, because that's all the language has.

So either you don't target javascript (which would be a bit silly in the case of JSON), or you go the other way and forbid integers, even in languages that do support them. Which is also kind of silly.

Ultimately the real issue is that javascript doesn't have integers and if you're interacting with it, you need to be aware of that, JSON or not.
