With this security model it is in essence no better than plain USB flash drive. I would assume that adding at least some protection against physical attacks could be reasonably simple and would greatly expand the usefulness of the device (eg. making it somehow inherently tamper-evident and replacing the DFU bootloader with something custom and open that does the same thing as RDP Level 1, but without the bricking risk) |

I disagree. With the right firmware, the SC4-HSM can securely generate keys that cannot be compromised without decapping the chip.
