This appears to only support direct binding, and not as subclass

Not sure how this works in Kodein, but if you bind to the Concrete Class for example, and the constructor accepts the implemented Interface, your type check is == so will not bind. Is there an internal call you can make to Kodein to have it do the same logic it would apply?

Basically calling its instance<type>()?

Not 100% sure what you mean here, mind giving some example code?

Closed, this is default functionality of Kodein.
