[arin-ppml] Policy Proposal: Equitable Distribution of IPv4 Resources before IPv4 Run out

Can you help me understand the rationale for this proposal a bit better?
As I understand it, this proposal would "lock in" the size-based
distribution of addresses for the remaining ARIN free pool when the IANA
free pool is exhausted. That's straightforward enough, but I'm a bit
unclear as to the "why". How does locking in such ratios, and reserving
space for each group, help ensure a more equitable distribution?
