Or is it not so much because IPv6 is inherently more secure, but rather because its support is still pretty bad outside of the main computers ?
Or because random house appliances are not a particularly interesting target ?
The so-called smart devices doesn't follow the standard security protocols anywhere close to computers and mobile devices.
Is it? Don't most consumer routers come with a firewall configured to block incoming IPv6 connections?
This is in the context that those ISPs are boasting 90%+ IPv6 coverage, which makes up for tens of millions of residential customers !
Otherwise, this is more hearsay from discussions about this on technical ISP forums, I wanted to look more into this, but I'm waiting until my ISP gives me more than a single /64, and with proper router support (so I can easily do things like host my server separate from my home network).
My point was more "The tools they provide for IPv4 are crap, so wouldn't you expect the tools for IPv6 to be crap too?" with a side helping of "Just because they don't show you any (good) UI doesn't mean it doesn't exist". I agree that ISP-provided routers suck for both IPv4 and IPv6 configurability, maybe a bit worse for IPv6, but in my experience I've never seen one that both enables IPv6 by default and allows inbound traffic.
