On your product sure, on the evaluation board that's more questionable.

When an evaluation board's user reach this sysfs entries to do a write
to it I believe that's not a random choice but a user's choice.

Maybe adding a otp_unlock entry to the sysfs before allowing write could
secure more the feature when running on the evaluation boards so that
the user can think twice before writing to the fuses.

Best regards,
