It does?  Even in the traditional BSD disklabel scheme, only the file 
system that resides in the partition that "overlaps" the label area is 
going to "have access to" that disklabel.

Once we are fully transitioned to wedges, I don't expect this to be a 
problem, since the "whole disk" method will be via a different block 
device (e.g. /dev/sd0), not via the individual wedges.
