I looked back at this and noticed I should have said "the right
matrix" is more important.
Still, I'm a little surprised there's been no response from a
comparison of a DNS Operations WG document to real-world measurements.
Are we okay with a document that issues criteria that only 70% of
TLDs fall into "green?" Are the grades overly harsh? Should the
TLDs be urged to work on getting to green?

For kicks I ran the included perl code against the 313 delegations
from the root zone (313 does not include "root" and does include the
11 test TLDs).
...I'll leave it to the draft to explain the headings and rankings
below. I did this just to measure the draft's assessments against
the TLD settings. Not that the TLDs are the only audience of this
draft, but it's a convenient data set.
Measured in %'ages of 313:
Max length domain name || Average length domain name
Color A-only A+AAAA A-preferred || A-only A+AAAA A-preferred
||
Green 59% 19% 19% || 99% 69% 69%
Yellow 35% 41% 18% || 1% 31% 28%
Orange 4% 21% 9% || 1%
Red 2% 11% 53% || 2%
The left matrix is more important (operationally). That's about
the only commentary I'll add, just to head off the concern of "red"s
in the right matrix.
To Paul and Akira, here's more or less what I did with the results of the pl:
looping through the names in the root zone:
server_set=`dig @127.0.0.1 +short $name ns`
size_estimate=`perl respsize.pl $server_set`
results=`echo $size_estimate | sed "getting '()'s#$name \2 \3 \4
\6 \7 \8#"`
echo "$results"
and then used a spreadsheet to do the percentages. (Shown in case I
messed up something.)
