yes, I think that is what we want to toggle. Because there will be users
who are not interested in LSPP and just want regular ipsec behaviour. 
By default, we want regular ipsec behaviour which would be to accept 
all unlabeled packets. And the toggle can be used by sysadmins to enable
"LSPP behaviour" as you have stated above. 

Where would the policy boolean go?
