DRAFT: If RBR event applier uses a secondary key or a full table scan to locate a row, force waiting for prior commit to complete.

I think if you wait_for_prior_commit() also for secondary key case, you should definitely restrict it to be only for conservative parallel replication, not for optimistic/agressive. Using a secondary key seems generally fine (as opposed to full table scan), and this problem should affect only conservative mode, no need to penalise optimistic/aggressive. (But maybe that is what is meant with "DRAFT"). - Kristian.
