Setting up the DSL upstream can be a rather slow procedure if the signal level 
on the line is close to the technical limits. Cable connections can sometime 
just fail... and when they get up again, they might renumber. And what if the 
upstream connection is down for so long that the GUA prefix times out?

As far as I can tell, provisioning a ULA always, regardless of the GUA is 
actually simpler and less failure-prone.
