Honestly! From a non-corporate perspective this sort of thing is a welcome development. The constructive concern is whether this might enable coreboot/libreboot on newer generation processors, and if not then whether it's ergonomic enough to at least enable widespread neutering of AMD's built-in trojans. (PS if you're worried about the illegibility of your computer's storage devices and your resulting inability to completely wipe it and reinstall, then that sounds like a problem with your motherboard!)
