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.
