This is awesome! the json types part is perfect. If I found your fork earlier I would have just used that as its what I need for jsonb.

The dates solution I fixed in a rest API wrapper on the client side. It's not great but it hides away the date serialisation issues

Is it performant? Not really. But it stopped us from having to deal with the string issue which worked great.
