Question about "19.28 release Update Known Issues (Doc ID 19202507.9) # 1.13 Incorrect results ..."

I have a question about Doc ID 19202507.9 # 1.13 "Incorrect results may be returned when using "ORDER BY" with parallel execution and rowsets enabled."
I think that every Oracle 19.28 database and its associated applications could be affected.
Does that mean that after applying the 19.28 RU patch, we should implement the specified workaround (alter session set "_px_single_server_enabled" = false; ) in all databases?
And if so, then it certainly makes sense to implement it with "alter system set "_px_single_server_enabled" = false;"?
