Agreed. This has long been one of Fedora's strengths compared to other distributions. 

However, the initiators of the change proposal (almost?) all come from server type variants, especially cloud. On the one hand, they want the option to configure via DHCP back again, and on the other hand, they want the option to explicitly leave the hostname „unconfigured“ = "localhost", because this triggers various post-installation tools that automatically adapt post-installation tasks to adapt the system to different runtime environments. The unconfigured hostname thus paradoxically becomes practically part of a fully configured installed system.  

At least that is how I understood our discussion.

Yes, for desktops und specifically laptops an unkonfigured hostname is generally bad. But, the current situation having a network with dozens of Workstation all named fedora is similarly bad as all named localhost (before the switch to fedora). 

So we might have to handle this differently for desktop type and server type systems.
