So you guys keep combining IPv4 and CGNAT.  These two things are not the same.  They do not require each other.  If you're small, you get space straight from ARIN (I got mine in January 2022).  If you're big, buy a block (after completing an ARIN ticket!)  If you don't want to pay for a big v4 block, then do the cheaper thing:  v6.  But you're still deploying v4 anyway, it'll just be with (CG)NAT.

For me, I see 0 value in v6.  I do see customer issues and I have experienced v6 (dual stack) issues myself.  So when I have customers demanding I get them FTTH every day and 0 customers demanding I get v6, which do you think I'm going to do?

Asserting that IPv6 shouldn't be a priority because 'nobody asks for it' is specious. What if customers saw Cloudflare's "isbgpsafeyet" site and demented you stop running BGP because it's "unsafe" ? Is that a valid reason?

Customers care about 1 thing only : Does it work when I want to use it, or not. And a lot of ISPs have learned difficult lessons in the last couple years when the small handful of customers who would complain that their work VPN didn't work behind the CGNAT boxes they ran turned into a heck of a lot MORE customers complaining.

I completely agree.

I get why line of business applications; e.g. billing, provisioning,
repair, haven't been updated to support IPv6.

But I believe that any network equipment vendor that is (or has been for
the last 1-2 decades) selling /new/ equipment really has no excuse for
not IPv6 not having feature parity with IPv4.

I've had similar lack of success with my municipal GPON provider.  At
least the people answering support tickets know what IPv6 is and know
that it's on their future list without even being in planing / testing
phase.
