Did I miss something? :-) No, you didn't ;) In fact, I even think recent MacOS (or is it MacOS X ?) may create pure HFS+ volumes without the wrapper. The main reason for the wrapper was for machines running non-HFS+ capable filesystem to display something (where are all my files gone ?) instead of proposing you to format the disk, and for the system to be able to boot from HFS+ since OldWorld ROMs didn't understand it. Basically, the wrapper contains a slim-fast MacOS System file which contains the necessary HFS+ support to mount the real volume and continue booting from that.
