Well - it’s meant to be able to install everything, by pulling it from the network 
A purely text-mode installer could provide all the same functionality.
Remote-only would be interesting. But the use case I was thinking of was just “boot your desktop/laptop into the installer USB, and do a custom Fedora installation pulling packages from the internet”. It would be nice to have a smaller ISO that can do all that in text mode, without all the machinery to provide a browser-based GUI.
