That had been done in the patch committed along with my reply mail:

I was saying that there is the test's specific logics that changes the
slave side unilaterly. After my changes taking the test as it is
causes row-based replication to stop at with error due to
inconsistency. Previously, at time of the idempotent default reign,
that fact was not discovered as the error was ignored.

Actually, as discussed with Mats, there are lots of places
when the macros can be deployed. Please check our mail thread.

I doubt there is a standard for the case we are having: the fact of
