I do fresh installations more often than upgrades so the older way was better for me. The lower picture is from version 1909. 1803 had 500MB size wich had caused a second recovery partition. It would have been nice to have a 600MB partition for recovery first instead so we have some margin. Disks today is big enugh for that.
