Guess what, that shouting gave you CIDR and NAT which dramatically
slowed the address consumption.  There was no "Crying Wolf".  If
the way addresses were being consumed hadn't changed we would have
run out of addresses 2 decades ago.

I was running IP connected networks back then.  It was a real
problem.

6% of the world is using IPv6 today.  This is not a "pi.. ant minute
fraction of the world" unless you think 100's of millions of machines
is that small.

Pick a tunnel end point / broker closer to you or turn off Happy
Eyeballs.  This is measuring IPv4 native vs IPv6 tunneled to the
other side of the Pacific if you are using the topologically closest
HE end point.  It is not measuring IPv4 native vs IPv6 native.
