I do ... and have seen many "This is the year of IPv6" style statements,
which is not what I am saying.
And again, I am not saying IPv6 was perfect.  Are you saying you don't think
anything relevant has changed in the last decade?

Sorry, but I wholeheartedly disagree - I see that quite a bit has changed
WRT IPv6.
The protocol itself has been tweaked, the implementations of the protocol
have evolved, the deployment guidelines for both and the understanding of
all three of those things has been escalating rapidly over the last
~couple-few years ...

(Asnwering what I think you meant to ask ...)
Things hadn't progressed on some fronts (and degraded in others) to the
point they are at now.  As with any other fundamental change, it takes time
to reach a threshold (a "tipping point", if you will).  

Are there still certain failures in how this whole deployment (or some would
say, lack thereof) has transpired?  Sure.
Are there a few things that could have been done different (some would say,
better)?  Sure.
Are any of those deal-breakers?  IMHO, nope.  
In fact, "the perfect is the enemy of the good" - inaction due to certain
failings is often worse than the alternative.

I believe that is something of a strawman.  Naturally, if they were banking
solely on an all_IPv6_only_IPv6 world they are most likely no longer around.
I am not arguing for anyone to punt IPv4 completely, for quite some time
anyway.  BUT there are quite a few organizations that have been preparing
for, and some actually running native IPv6, for several+ years ... and I
firmly believe they will find themselves far more prepared for the time when
we reach that "tipping point", and thus in a strategically beneficial
position.

PS - I ask again, what is your opinion of all of these organizations that
are actively pursuing IPv6 deployments, encouraging environments to do so,
etc. ... ?
