Good question. Let's be pragmatic.
What are the chances of having formatting changes of the expansions we are talking about?
If the uplifted test would make sense, I think we should just accept them like that.
If there is any controversial, we can discuss that and decide how to move forward.
I'm open for all kinds of solutions, including removing some tests. IMO the formatting for expansions would be great, and a long awaited feature that worths serious consideration.
