secureboot is coming whether you like it or not. You may be able to disable secureboot in the bios, but every bios vendor will implement it differently and some may forget to implement it at all. How do you tell a new Linux user that they have to hit F11 or maybe Delete or maybe F2 during the first few seconds of boot and then wade through a bunch of bios menus to disable a feature called _secure_ boot (let that sink in) just so they can try out this new Linux thing. Kind of a high bar. Realistically you need to support secureboot if you want your OS to be accessible to a wide audience.
will it be possible to just flash a coreboot with flashrom over the BAD and EVIL UEFI ?
