After reading this, I swing back to the position of thinking 
$undef_ref_ULA-C is a bad idea *IF* PI space is freely available to 
all comers, not just multi-homers.

But if routing fears cause PI space to be restricted, then I am still 
sympathetic to network-layer-scoped addresses.  Still I am losing 
faith in scoped addressing above layer 2 (i.e., except link-local) 
will ever be beneficial.
