      From the previous discussion, we understand there will be 2
      possibilities when we enter the final /8: 
      
      Case 1: 
       If the Secretariat reserve the final /8 from IANA for use in the final /8 policy, 
         at some point, any unused space reserved for special use (IX, CI, etc) 
         may be released for general allocations and assignments, after they are all 
         allocated/assigned, we enter the final /8 phase.
      
      Case 2:
        If the Secretariat doesn't reserve the final /8 from IANA for use in the final /8 policy,
         we enter the final /8 phase when the total of remaining address space is less than a /8, 
         in this case, the remaining space in the reserved block 203.119.0.0/16 become 
         part of the final /8 space, and the final /8 policy applies to it. 
      
      In either case, critical infrastructure assignments are no longer possible because 
      all previous allocation and assignment policies (including CI assignments) 
      become void when we enter the final /8 phase.
      
      From the previous discussions, most people tend to feel comfortable with 
      'Allowing Critical Infrastructure assignments from the current reserved block 
      until it runs out'
      
      So, in Case 1, in order to continue to provide CI assignments, we may propose
      'Not to release the CI block for general purpose, allow Critical Infrastructure 
      assignments from the current reserved block until it runs out'
      But that seems impractical as a policy statement, theoretically speaking, it might 
      produce a deadlock as we have a /8 plus some thing and cannot trigger 
      the final /8 phase. 
      
      So, in Case 1, I will suggest:
      
      -Continue to allow CI assignments according to 11.3, "Critical infrastructure" 
      -Let the Secretariat decide the best way to accommodate new CI assignment when we 
       enter the final /8 ( We may state this explicitly, but I feel it's unneccessary, any suggestion? )
      
      In Case 2, the remaining space in the reserved CI block become part of 
      the final /8 space, in order to continue to use it to provide CI assignments,
      we have to continue to allow CI assignments according to 11.3, "Critical infrastructure" 
      
      So, looks like the current text of the proposal already address the above 2 situations.  
      Given the current CI statistics, and consider there are 16K /22s in the final /8, 
      allowing CI assignments will NOT have significant impact to the final /8 allocations.
      
      Any one has any suggestions? 
      
      Thanks & Regards
