Well, yes and no. We don't *need* to hack them, but it is sort of
necessary if you are going to get maximum benefit. The reason people
like me fight for domain literals in the first place is so that we can
function in environments where there are weird holes in the
DNS. Needing an intact DNS to resolve the literals obviates all the
benefit. However, the hack in question is really, really simple, and
need only be done on v6 mailers.
