When I was first looking into IPv6, people were talking about how you can self-assign an address by simply wrapping an IPv6 address around your MAC address. But that practice seems to have fallen out of favour, and I'm guessing the reason is, as you say, the whole privacy thing? There's a lot of pushback these days against any tech that makes it easier to fingerprint your connection.
That was so insane - "we need a unique number, let's just use the MAC" - it was like people didn't even think through any of the implications when making ipv6 address schemes.
Similar with the address proposals that ignored the need to minimise the size of core internet routing tables.

Noobie question, wouldn't the ISP decide what your outgoing IPv6 address is? Like they do with IPv4? I mean no matter how many times I restart my router, my public IP remains the same so I always thought it was assigned by them.
For reference, in the US, Comcast only gives up to a /60 for residential connections. It's still fine for most use cases, but it does feel a bit like doing a bit of penny pinching when you're wondering if you have enough /64's for how your network is going to be set up.
Yeah, fortunately, for my own use cases, /60 is enough, but I can't think of a good reason for Comcast to not give out /56 since they're pretty cheap compared to IPv4.
