Currently all Krossbow interfaces still use the old scheme generating a DefaultImpls class with default implementations as static methods. This is not ideal, and we should eventually move to real JVM default methods (since we target JDK8+).
However, this change is binary incompatible, so we should keep generating the old DefaultImpls classes. This is what the -Xjvm-default=all-compatibility mode is for.
