Review Comment:
   Why not "0L"? As I can see almost all places in our code uses "0L"

Review Comment:
   F.isEmpty()? Should we check it for null here?

Review Comment:
   I'd suggest to rename it, because it annotates class, and  "parameter" looks 
misleading. WithCliConfirmParameter? RequireConfirm?
