We assign IPv6 deterministically. Incrementing them is the most boring way to use IPv6 space.
You can also just start in the middle of a block and make a sequence of 10,000 IPs effectively unguessable.
I don't buy that keeping addresses private has much value, but IPv6 still isn't worse than NAT in that respect.

SLAAC has an option to randomize, but it's a lot slower than per-connection.
And anyways, when you have a NAT you're probably routing traffic through a level 4 balancer or jumphost or using a VPN somewhere in your LAN.
