Details

From the changelog of systemd-203:

* nss-myhostname will now also resolve "localhost"
implicitly. This makes /etc/hosts an optional file and
nicely handles that on IPv6 ::1 maps to both "localhost" and
the local hostname.

This means that the hosts file no longer needs to be shipped in new installations but instead could be strictly optional. Removing it from the filesystem package allows to get rid of an additional configuration file.
This task depends upon

I see no compelling reason to get rid of this. nss-myhostname is still our fallback when the hosts files doesn't exist (notice that 'files' is the first priority in nsswitch.conf). Getting rid of this file only to potentially bring it back under package manage control somewhere in the future is potentially painful.

Lack of a hosts file may cause programs to misbehave, and in strange ways -- apache is one of them, I'm sure there's others.

Big -1 from me.

-1, nss-myhostname "fallback trick" does not work nice when your "internet" connection fails. Personally I disable it.
