Yes, exactly, which makes the claim even more baffling.
Sure, they can just reimplement all their Java dependencies, but if they have to implement e.g. collections anyway, they could just have designed a better API in the first place, instead of being stuck with Java collections on platforms that don't even run Java.
I think you can't have it both ways, having a worse abstraction for handling errors while claiming that it works better with Java code and then claiming that "pure Kotlin code" is where the more interesting case is.
