IPv6-only subnets and EC2 instances

Is that really what's happening? It gives each device an address which is unique at the time but those devices get new addresses periodically when the network configuration changes, they roam networks, etc. and there's no global registry linking addresses to people or even the same device.

From another angle, most people are walking around with a globally-unique identifier (IMEI) in their pocket with all kinds of sensors. Does using IPv6 materially change the situation for any attacker?

In IPv4, dynamically leasing different IP address by connecting is a mitigation of lack of address stock (at least dialup from PC era, I don't know how much effective in router era). In IPv6, ISPs don't need to do that so they can just lease dedicated IP block to customer. Then they don't need logging IP-to-customer-by-time for investigation.
