I suspect the answer to that is "technically it doesn't - but how are you going 
to interact with the hypervisor without it ?"

By default, many many things (eg network and emulated storage) are routed via 
Dom0, and you need a way to interact with the hypervisor (eg start & stop 
virtual machines). AIUI you can switch at least some of these to use another 
DomU - but given the current design, you still need Dom0 to control the system.
