But that's not specific to golang. You can use the same approach in Java, Kotlin, C#, etc

Unless I'm missing something, you then have to write wrappers that translate between the big and the small interfaces, or explicitly mark all interfaces as implemented at the original type definition point.

The first one is a lot of boilerplate, the second one is not always possible.
