gnome-control-center added a Recommends: libnss-myhostname years ago so that it was possible to easily change the hostname in the Details panel. That dependency no longer appears to be needed.
Testing Done
============
In both Debian Testing and Ubuntu 18.04 (Debian doesn't use systemd-resolved so seemed useful to try there too).
sudo apt uninstall libnss-myhostname
Restart
Open the GNOME Settings app (gnome-control-center)
In the left sidebar, click Devices
Enter a different Device name in the block
Open a terminal and verify that the hostname has been changed.
Other Info
==========
There are concerns about having libnss-myhostname in the default install. See comment 5 at LP: #1741277.
See also LP: #1162475
Note that /etc/hosts isn't updated regardless of whether libnss-myhostname is installed (I guess my bug description there was wrong but there was some kind of bug there.)
Regression Potential
====================
I believe most distros do install libnss-myhostname as recommended by https://www.freedesktop.org/wiki/Software/systemd/hostnamed/ As long as things appear to work, maybe we can ignore that recommendation. |

Regression Potential
====================
To quote from the manpage:
https://manpages.debian.org/unstable/nss-resolve
"Note that systemd-resolved will synthesize DNS resource records in a few cases, for example for "localhost" and the current hostname, see systemd-resolved(8) for the full list. This duplicates the functionality of nss-myhostname(8), but it is still recommended (see examples below) to keep nss-myhostname configured in /etc/nsswitch.conf, to keep those names resolveable if systemd-resolved is not running."
Ubuntu uses systemd-resolved by default and it's expected that users who don't want to use that will need to configure some things manually. |

Impact
======
gnome-control-center added a Recommends: libnss-myhostname years ago so that it was possible to easily change the hostname in the Details panel. That dependency no longer appears to be needed since we switched to systemd-resolved.
Test Case
=========
sudo apt uninstall libnss-myhostname
Restart
Open the GNOME Settings app (gnome-control-center)
In the left sidebar, click Devices
Enter a different Device name in the block (let's say new-hostname)
Open a terminal and verify that the hostname has been changed.
Then run ping new-hostname and verify that that command works in the terminal.
Other Info
==========
