Will we be able to get dict type attribute with HAPI?

Still not here even in 4.2

I think it can be really useful, especially for integrations. I'm currently using dicts in unity but I have to flatten them to strings.

I suppose it's not an atomic type for engine and dicts are basically json with a view implemented on the client.
Actually I wouldn't mind if engine gives me just typed json as a string for dict attribute so I don't have to care about it beforehand.
