Because it's part of the original SCSI standard and as a standard, all 
sensible devices comply and are backwardly compliant.

There are occasional applications when you might want to connect two 
host adapters to a disk so it must be possible for the host adapters to 
have a unique SCSI ID. One (scary) example is the old CMS SCSI card for 
the Apple II series that allowed two or more computers to share a 
single disk. For obvious reasons, only one computer could write at any 
one time...
