Knowing CCP (… or believing to know) will they implement the first part, but possibly skip the “POTENTIAL:” part, because their main goal is to increase player activity.
Why do I believe this? The big warfaring corporations do all have structures and they wouldn’t be affected by it, but groups such as RvB might have a problem and require a structure if they don’t have one already. The addition of the second rule would also imply that destroying a corp’s structures ends their war. This is again more of a problem for the smaller corps and could again dampen their activities. It could even motivate a destruction spree by the big warfaring corporations against smaller ones in order to secure their dominance.
CCP will be looking at their data and decide from there how likely these risks are and what their effect on their goal will be.
