I don't think the plan itself will change as a result of applying this
patch. You might however be able to observe some performance improvement.

I could see no performance improvement, even with 16 separate queries combined with UNION ALL. Query performance was always with +/- 10% of a 9.6 instance given the same script. I must be missing something.
