this seems to make sense to me. to get there we will have
to figure out how to provide pf(4) with hint to indicate
IPv6 address is deprecated. pf(4) currently keeps addresses
assigned to interface in radix table. It is unaware of whether
particular address is deprecated or preferred.
:1 does not read intuitive. I think we should just introduce
a modifier named :preferred. But the biggest hurdle is to
figure out how to let pf(4) know about IPv6 address state.
