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.
