Ok fair point so let me explain as this is the key point for why I suggested the amendment.
Lets assume that the technical values and requirements for Anycast is valid..
The current requirements for a minimum ipv4 allocation of /24 is that the requester can prove that they will be able to utilise a minimum of /25. This is to encourage end users to rather use space allocated by their ISPs.
However the technical requirements for Anycast can not be bound by a /25 limitation. An Anycast service can be delivered using a lot less address space than a /25. But the limitation of a /24 in the ISP realm can not be altered.
Thus given the current requirements (minimum of /25), I either need to fabricate address use up to a /25 and show Serial numbers of devices (which given virtualisation is easy to confuse) or a simple addition to the policy will allow /24s to be allocated to SaaS or NaaS providers with a valid Anycast design and need.

>> Any NaaS or SaaS provider that is limited to deploying IP based services (i.e. Not DNS or Appliance based) will likely need Anycast. Redundancy via cloud-based systems will involve deploying an Anycast based model. One example would be to deploy servers in DCs in South Africa, Nigeria and Kenya, Anycast will allow for redundancy and proximity to services.
>> Example: 1. Various African ISPs do not allow core routing/switching platforms to make use of DNS lookups. How will you provide redundancy for syslog/snmp traps/VTY ACLs/AAA//DNS SEC, Auth and cache etc etc if you were a SaaS provider of these platforms?
