> I've had less than 0.5% of customers ask for IPv6 from my fibre ISP
How many ask for IPv4? I understand your situation, it's a lot of work, for something that many won't notice. It's just that saying there's no demand because your average consumer, who also doesn't know what IPv4 is, isn't asking for it, is the mentality that keeps IPv6 from being implemented.
On the funnier side of things, we've also sometimes run into the opposite problem that we can't reproduce an issue, because it's only on IPv4 and 95% of the time everything we do is IPv6. But we're also not serving home users.
Static IPv4 addresses are closer to around 5% of customers. Nobody asks for IPv4, but some customers bring their existing or own wireless routers along and occasionally choose devices that are not IPv6 capable. Maybe in another 10 years those devices will finally be fully removed from service. The worst stragglers right now are the old combo DSL modems that effectively have no modern replacements -- it's just not worth spending money to replace them when customers are going to migrate to fibre soon enough.
I don't think GP meant static addressing but literally, how many ask for IPv4 service? None, because you just provide it; it's an unstated expectation.
Now apply that to IPv6 and you can see the point that (I think) GP is making.
Side note: The claim it is not widely used doesn't track. How many people use Google or Facebook? More than half of that traffic is over IPv6.

So when you said `ask for IPv6` you meant `ask for a static IPv6 prefix` or something else similar to a static IPv4 address? Or is this an apples to oranges comparison?
And then you say `Nobody asks for IPv4` - so nobody asks for IPv4 and 0.5% ask for IPv6?
