Now that more and more devices are built using eMMC, providing a way to easily flash the system without too much hassle seems like a right thing to do. Since fastboot is the most deployed tool to do that these days, we can just rely on it to provide a way to flash the various components in the system (SPL, U-Boot and the system itself) easily, especially since you can upload the U-Boot hosting the fastboot "server" through FEL.
