Hi,

If X and Y are mutually exclusive, a document saying "X SHOULD BE DONE"
is effectively implying "Y SHOULD NOT BE DONE".

Right?

(And do not tell me that people would do DHCPv6 IA_NA/IA_TA *and* SLAAC
on the same network - technically you could, but nobody would do that,
given that it voids the reason *why* IA_NA/IA_TA are used: control, DNS,
etc - note I'm not saying "security")
