Yet, while people keep saying that, ipv6 adoption only goes up every month. I'm having a hard time accepting "the ship has sailed" while my home outbound connections use ipv6 for more and more endpoints.

Yeah, definitely. I made a mistake a while back, and swapped one of my testing networks to v6 only, and I was surprised I only noticed things were broken after a few days (looking at you github).

I think it has a lot to do with people being put behind cloudflare etc, and getting v6 basically for free

I think businesses are holding up wider V6 deployment. In a lot of them that I've worked with, you don't talk about v6 as it's either a thing no one wants to learn or has no value worth implementing.

meanwhile in the SP world, most core networks can support IPV6 quite trivially because it is either just another payload that is labelled and put into an MPLS environment, or when we need connectivity for our own nodes, it is quite trivial to achieve. (especially if you run BGP or IS-IS as an IGP).

IPV6's address space starts to make a hell of a lot of sense when you look at microsegmentation. And by that I mean you don't need to deploy carrier-grade NAT behind your firewall to mask reuse of one of IPV4 class A networks.

All the cloud provider VPCs seem inextriciably linked to IP4 config, which seems to work great. Maybe the low level infrastructure is IP6, but we dont operate at that level.

I'm starting to think the cloud providers are hoarding IPv4 addresses and see them as an asset, and don't want to "rock the boat".

starting? :) - definitely are. It is also a chicken and an egg problem - until people start shouting they won't implement v6, and people won't want it until there is a reason too (like not getting v4 addresses - which cloud providers solve by just NATing the world)

AWS supports IPv6 on non-default VPCs: https://docs.aws.amazon.com/vpc/latest/userguide/get-started...

I have a hobby project on AWS using it today, with multiple EC2 instances having IPv6 addresses. It works beautifully.
