I've noted that on a variety of machines /etc/hosts finally do get

127.0.0.1 and ::1 ?
For consistency it should really have localhost defined and ip6-localhost
be optional. However, the distinction is not likely to be visible to most
end users anyway so it shouldn't matter too much. Anyone configuring an
app to bind to 'localhost' explicitly should probably already be aware of
what their system (or local DNS) considers 'localhost' to be and whether
the local apps that are talking to each other can do so over IPv6 vs IPv4.
