We would sometimes ignore localhost-style names in /etc/hostname. That is brittle. If the user configured some hostname, it's most likely because they want to use that as the hostname. If they don't want to use such a hostname, they should just not create the config. Everything becomes simples if we just use the configured hostname as-is. This behaviour seems to have been a workaround for Anaconda installer and other tools writing out /etc/hostname with the default of "localhost.localdomain". Anaconda PR to stop doing that: https://github.com/rhinstaller/anaconda/pull/3040. That might have been useful as a work-around for other programs misbehaving if /etc/hostname was not present, but nowadays it's not useful because systemd mostly controls the hostname and it is perfectly happy without that file. Apart from making things simpler, this allows users to set a hostname like "localhost" and have it honoured, if such a whim strikes them.
