> Both IPv6 and Wayland have increased complexity and surface area for pain (cost) without an obvious benefit for the end-user.
I'd argue the opposite: IPv6 has lowered complexity for the end user: SLAAC, endless addresses, no need for CIDR – these are all simplifications for the end user.
> Also: wrt IPv6 specifically, I don’t believe every device on a private network should be publicly addressable/routable. To me that’s a bug, not a feature,
Some would argue it's a feature. But let's say it's not useful. It's still surely not a bug. An address being publicly routeable doesn't mean you have to route traffic to it. Just don't, if you don't want to.
> and again does not serve the consumer, only the producer.
I'd argue that it simplifies some things for the consumer (see above), and also lets the consumer be a producer more easily. I'd argue that that's a good thing, more in the spirit of the internet. But even if the end user doesn't care, it's not a detriment.
