Of course address assignments should be documented.

But for a metric to be useful, you have to be able to measure something,
and use the result to judge something.   And IPv6 address usage is NOT
useful to judge anything (mostly due to the /48 rule).

Again: the amount of address space (what is "address space"?  Single IPv6
addresses, or /48s) doesn't define the importance of a network or anything
else.

Compare an @home-type network with 10000s of /48s given out to customers,
each of the end customers using only a handful of IPs, to a research
network, giving out 50 /48s to 50 big universities, each of those using
100000 IPs per /48.

Which one is making "better usage" of their IPv6 address space?  Which one
should be given an application, and why?
