Jan's comment is why should others care what he wants because it has
zero impact? I am saying the community cares because we have to
maintain the code. I stand by my comment.
I remember a dismissive comment by Jan when 'session_replication_role'
was added, and a similar strong comment from me at that time as well.
It seems we are doing this again.
