Possibly print the route for each returned record (minimizing to only
show each path once would be a bonus).  The bigger thing that got me
thinking about this is that there's no way to say "show route <host>"
and see the IPv6 route instead of the IPv4 route (for the case of a host
with just one A and AAAA record).  I guess JUNOS does the DNS resolution
and picks what to look up before it gets to looking at what table you've
asked for (so adding "table inet6.0" doesn't work).
