"Minimal" will contain the least amount necessary to install the OS. We also prefer off-line installs with minimal which would remove options to download updates or install 3rd party software during install. This requires adding language packs to the iso when using minimal.Why could this not be a variation on the OEM install type instead?
 Hostname is currently on the "Who are you?" screen. It uses the username and DMI information to populate the hostname. We propose using the same DMI information, adding 4 hexadecimals to the end (a checksum of the MAC address "Galag-Pro-A8F3"), and moving the hostname up to the "Installation Type" screen. This enables "minimal" installs to set the hostname and business customers can install the OS on multiple machines, with automatic or custom hostnames, then give the computer to their user for account setup.What would setting the hostname earlier actually bring as a benefit?
Could you come up with a code branch that does what you want and knows to install GNOME Initial Setup, or with a pre-made image that mocks up how you see things, so that we could play with it?
