That kind of implies we stick with the current policies as-is.

While this data would be useful, I'm not sure how it will help LIRs  
with their planning. How many LIRs know now (or soon) what their IPv4  
needs will be once IANA runout is reached? Will they share that data?  
Will it be truthful? If I was an LIR, I'd be tempted to inflate my  
post runout needs in the hope of getting an extra chunk of the then  
scarce and valuable IPv space. Partly that could be justified by  
conservative engineering. OTOH it could be for baser motives: like  
getting extra space which can be traded.

Even if accurate run-rate data was available, it would inevitably be a  
snap shot and inherently out of date. And it would undoubtedly  
influence LIR behaviour. Which would have an impact on run-rates. My  
guess is this would promote depletion of the remaining v4 space, but  
not necessarily in a fair way.
