Do I have to use interfaces for my services? I strongly disagree with this line from the Kodein docs:

In DI, each business unit will have dependencies. Those dependencies should (nearly almost) always be interfaces.

So I am wondering if Kodein is a good choice for me if I don't have silly interfaces for every single dependency.

You can bind any type. They don’t have to be an interface.

You can use "from"

The documentation says should not must, so you can happily ignore this tip if you want to and use concrete classes instead of interfaces
