How often do Fedora users boot their systems to even justify the discussion about making the boot process prettier? As for me, I don't mind seeing the GRUB2 menu for a few seconds - the BIOS part of boot is not pretty nor fast, so removing the GRUB screen does not help. And it should be visible anyway on systems with the serial console (or an IPMI console) attached. And I tend to suspend my laptop instead of shutting it down, so I reboot for kernel upgrades only. I really don't care whether it takes 20 or 25 seconds to boot, or whether there are two or three mode switches.
Also the car analogy in TFA is flawed - removing the car hood altogether create the functional problems (e.g. aerodynamical) instead of purely aestethical problems, which is the only problem which causes keeping the GRUB menu. I am glad that my car displays various things during startup instead of just "You may start the engine now" or "Oh no! Something has gone wrong!" (GDM pun intended).
I'd rather see Fedora to focus on restoring Anaconda into usable state (i.e. supporting more than one DE install, and support for custom disk layout including MD RAID and LVM on top of each other, etc.). There are _way_ bigger problems to solve in Fedora than how many graphics mode changes occur during the system boot.
