Why not reporting Throwable's cause (if present)?

Why not reporting Throwable's cause (if present) instead of the unhandled Throwable itself? For example, when unhandled exceptions are thrown from coroutines, we get "CoroutinesInternalError: Fatal exception in coroutines machinery..." reports instead of the actual cause of the exception (for example an IllegalStateException generated by a check(...) call); wouldn't it be more useful if the actual cause is reported?

I've managed to do that by overriding the crash method of the iOS CrashHandler:

    override func crash(t: KotlinThrowable) {
        t.printStackTrace()
        super.crash(t: t.cause ?? t)
    }
