None of that has anything to do with what you said in the post I replied to. "Add an extra octet to v4 addresses" has hard technical barriers to deal with if you want it to work, regardless of what the world looks like or what you're designing for.

> We now know that the "internet of things" and "having your fridge online", as well as "5G in everything so people can't firewall it off" is just insane and malign

None of this is really relevant either. IP's job is to handle the addressing used when sending data over the Internet, and it should do this job well regardless of what people end up doing with it.

> We also know that tying an IP address to a person (compared to an ISP using NAT) reduces privacy

We don't tie IP addresses to people. PI allocations might sort of count, but regular users don't get those.

Of course not, why would it? I quoted what I was replying to, and all of my comments made perfect sense in that context. In that context, I was discussing the winning ipv6's original design considerations, and yes "IPs for everything" was one of them, hence me talking about it.

I intended the quoted part to mean something like "they did consider adding extra octets to v4 addresses and setting those octets to zero to mean v4".

It's not like they weren't able to come up with that idea. It's just that if you follow that train of thought through to its conclusion, you'll either decide it can't work or you'll make enough changes to end up with something that works basically the same way v6 does.

But yes, having enough IPs for everything was obviously a design goal. It would be excessively silly to go through all the work to increase the address size and not increase it by enough to handle whatever people ended up wanting to do with it.
