Thanks for working on this! Its unclear at the moment exactly how we are going to handle this, since the end goal is to be compatible with as many versions of Hive as possible. That said, I think it would be great to open a PR in this case. Even if we don't merge it, thats a good way to get it on people's radar and have a discussion about the changes that are required.
