Are you sure it's false?
I don't see an explicit check in alternatives.c for the main kernel
vs init sections and with CPU hotplug the alternatives can be applied
arbitarily after the system has booted. So it would just stomp
over the init text pages which are used for something else now.
I guess to make it safe you would need to teach alternative.c to
ignore init sections.
