Hi Daniel, Can you provide links to the patches and discussion you're referring to? It'll be easier to provide some feedback if we have the detail in front of us.
I'm all for improving performance for the Oracle backend - as long as backwards compatibility or correctness doesn't suffer. If either of those are concerns, perhaps we can find a way to overcome them.
