I guess it's obvious they had different techniques for measuring the impact
of their changes.... Can you point to published studies where the root and
.com server operators analyzed Todd's questions?

"didn't notice a problem" is woefully insufficient here.

how carefully was this measured?  how was it measured?  across what
diversity of traffic.  what was the threshold for "a problem" here.

different use cases have different tolerances for the kinds of bad user
experience that google is concerned about here, both in terms of percentage
and in amount of impact.

As others have said, things will improve as more sites go dual-stack, and will enable dual-stack as soon as it's viable.  In the meantime,
we encourage our competitors to try. ;)
