I do not agree about someone else data modification. I think the NCC should
do the following:
1-inform anyone who asks for a block of networks that if different guarded
  fields are needed in the future then splitted blocks have to be registered.
2-only the same people who has registered the block can request the splitting.
3-inforce the above rules in database registration software.
