I was super surprised about ability to lift kernel lockdown programmatically, using sysrq_trigger file. I think it completely defeats entire point of the lockdown - it is like a safe with spare key duct-taped to the side, annoying but useless against any advisory.
The original kernel patch had a facility to disable programming lockdown lifting, but this apparently did not make it into the kernel he is using. Hopefully this was intentional, to make this less annoying for users during the testing period.
