This is my understanding too. My understanding is that eliding the StackMapTable attribute when there is no split-verifier is an optimization which can cause problems for agents/tools. So, the suggestion from Alex to simplify this by removing this optimization looks reasonable to me.
We can run more Runtime tests to make sure this does not break anything.
