Yea we usually try to keep backward compatibility for a couple of years (or until it becomes hard to maintain). Here's an example of how you could support two layouts: https://github.com/llvm/llvm-project/blob/25d1ac11d537debb217c65c2bcdd087a60cff58e/lldb/examples/synthetic/libcxx.py#L715-L718

I.e., call `GetChildMemberWithName` with the new name. If that doesn't work. Try with the old name. Let me know if you need help making this work
