I agree that this is happening today. Which makes me wonder, why is the
variable "security_ops" exported through "EXPORT_SYMBOL()" and not
"EXPORT_SYMBOL_GPL()"? It seems that people are taking advantage of
this and changing it would help slow them down a bit.

Chris, would you take a patch to change this?
