Use to assist injection to provide a default implementation for a certain component and reduce boilerplate in injector code. Argument class must be a non-abstract component class or a kotlin object implementing target interface. Avoid using when there is no clear 'default' behaviour for a component. NB: DefaultImplementation are *discriminated* during resolution of components, meaning that: - if there is exactly one non-default implementation and zero or several default, non-default will be chosen. - if there is none non-default implementations, default will be chosen Such configurations may arise, for example, for multiplatform modules: consider analyzing JVM+JS module, where JS contributes default implementation of some particular service, and JVM contributes non-default. If you need more fine-grained control of clashes resolution, consider using [PlatformExtensionsClashResolver]
