Not sure about everyone else, but I always put my hostname in /etc/hosts. Maybe that's from years of not always having DNS available back when the earth was cooling.
This behaviour plays havoc with templated VMs though or any time you can't be sure the IP there will be correct ...
At which point you start having to script fixing it etc or weird things happen.
I can't recall if it hit EL7 yet but Fedora has nss-myhostname so it'll probably arrive in EL7 eventually to ensure the local hostname is always resolvable to the system IP if it exists or at least 127.0.0.2 so stuff relying on gethostname() doesn't have issues and the older /etc/hosts shenanigans are not required.
