I've also seen parser directives inserted into the keys like `{ "fooBar__datetime": 123456780.0 }`, and many other creative workarounds

  Actually there is a common practice that java or js library used to serialize typed data. They just preserve the key starts with $ for special use So a class A with a double and and an int field will be something like { "$type": "A" "value":{ "a": { "$type": "double", "value": 1 }, "b": { "$type": "int", "value": 2 } } } And what about keys that actually starts with $? You just escape it with special $raw key "$raw": { "$escaped": { "$type": "double", "value" 1 } } It's a bit way too verbose. But given it is just a serialization format inside some library or app, it won't cause too much problems.
