FWIW, this isn't about making a Made for iPhone ecosystem for keyboards and mice. This is about the DMA features that are going to be in USB4 going forwards and that are already in Thunderbolt/Firewire/PCI Express. This security is specifically so that someone can't walk over to your machine, plug in a device, DMA all of your machine's physical memory to its flash, and then walk off with whatever data or secrets that are hanging out in RAM.
