David -

Note that the actual relevance of the total IPv4 free pool counter to practical IPv4 
address planning efforts will become moot during the same time period.

If you click on the total pool counter, the detail of the available free pool in terms of 
number of address blocks of each size is provided.  To the extent that is possible to
make _any_ meaningful strategic decisions in address space management based 
on the remaining IPv4 free pool (as it approaches zero), the information that would 
have any relevance in that process is the detailed breakdown of address blocks and 
not the total IPv4 space counter.

At the present time, we are focusing on high impact software development efforts 
that are actively sought by the community,  In light of the lack of community support 
for your suggestion and the fact that the information is already readily available to
those deem it to be meaningful, your suggestion was closed without further action.

We are likely to phase out the total IPv4 free pool counter and replace it with the
detailed address pool information upon hitting zero.  From that point forward, the 
detailed address pool information (and potentially some public summary of the 
waiting list status) is likely more meaningful to IPv4 address planning efforts of
those who have not moved onto the IPv4 transfer market or IPv6 for their network
growth needs.

Thank you,
