That is my interpretation also, but the DFU doesn't engage protection.
Running GnuK with a DFU bootloader present is completely not an option,
since both SWD and the DFU bootloader can readily hand you a copy of the
encrypted private keys on the GnuK. You would subsequently need to wipe
the DFU and after that engage readout locks. Which can all theoretically
be done by GnuK and reGNUal in concert.
