Hm, was there a certain scenario you were thinking of for this? In what case
wouldn't we want the HWM to consider the leader as well?
For what it's worth, I don't think this solution (by itself at least) is on the
table since it would not solve the case where a follower is removed from the
quorum and can potentially decrease the HWM. Just want to make sure I
understand your comment.
