Bug Description
hostnamectl is a System API that updates all important OS references to the hostname, so the operator does not need to know them.
Having to manually update /etc/hosts defeats the purpose of having the System API & leaves the OS in an inconsistent state

You could install libnss-myhostname (provided by systemd) instead of adding the hostname to /etc/hosts. libnss-myhostname takes care of mapping the local hostname to 127.0.0.1, so that listing the hostname explicitly in /etc/hosts is not necessary. See https:/
Ubuntu does not ship libnss-myhostname by default, so I see why one would end up adding their hostname to /etc/hosts manually. But, from the upstream perspective, it is not necessary for systemd-hostnamed to modify /etc/hosts, so I don't think there is anything to do here.
