Hi Simon,
I think this will be a new parallel path and this new path should be taken
only on kernel booted with secure boot enabled. (Either automatically or
by using some kexec command line option). So nothing should be broken
because we never supported anything on secure boot enabled system.
Thanks
Vivek
