I'm not a fan of it either but that is indeed the way things are done.
I'm sort of old school on this myself but Ubuntu does things
similarly...

127.0.0.1       localhost
127.0.1.1       srv2.azapple.com        srv2

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

so go figure and I sort of decided to stop fighting it and go with the
flow. It works fine.
