It would need to be an extremely small, well-contained change, that had no chance of disrupting other users of the capsule interface and where I had a good feeling that supporting it wouldn't turn into a maintenance nightmare (mountains of DMI strings or new platforms coming to market that used it). That's a tall order, and I'm pretty skeptical. Still, I'll never say never. Plus Ard would need convincing to give his ACK too. P.S. Has anyone actually investigated what would be required to fix the firmware to be able to extract the CSH if it was contained inside a capsule?
