I suspect a significant part of it is they don't actually *use* IPv6 internally or in their lab.  We have been operating our network with IPv6 for many years now.  I believe in most cases our connection to the management plane go IPv6 only as well.

Of course they're challenged. There's a finite amount of dev they can
do at any one time, and they go for what is going to make revenue. If
you tell them that the way to your wallet is to implement some new
feature in v4 and you're not emphatic that it be v6 also, they are going
to do the utterly predictable thing. If you really want to make progress
instead of bellyache, list off the features you need to run your network.

Better yet, deploy v6 instead of saying that you'll only do it when it's
perfect. That just tells your account critter that v6 isn't important to
you. I'll bet you'll find features that you want that are v6 specific
that you'd open your wallet for *way* before features that don't interest
you that you're requiring in the name of parity.
