You've left some 36 comments on this submission (which is honestly weird as HN usually rate limits to avoid that sort of aggressive participation), and your comments seem extremely...cherry picked. In another comment you dismissed the bandwidth savings of JXL because connections are so fast that eh, who cares, and in this case you herald the importance of progressive rendering because connections are so slow.

Are you the author of the submission? Literally never seen someone so motivated in a conversation before.
