This seems short-sighted to me, because the actual *advantage* of IPv6
is realized only when *incoming* connectivity is enabled (if it was
just about outbound connectivity, v4 would work as well).  If this
would imply that the communication between two nodes inside the 3GPP
network or communication originating from IPv6 internet and coming to
a 3GPP node could just silently fail.. this would seem to be very 
undesirable.
