It may be for people who haven't deployed it yet.

When you find a new technology which doesn't have that problem, please
let me know ;)

It's not my experience. Actually troubleshooting is much easier.
For IPv6-only devices it's just one protocol. For dual-stack devices
nothing has changed compared to a dual-stack setup.

Nor would IPv6-only.
When you made the decision to assign a single IPv6 address per device,
I assume you did evaluate pros and cons.
It doesn't make the  designs which are incompatible with your choice bad ones.

Dual-stack is expensive to operate, but if IPv6-only works, then any enterprise that wants to support IPv6 in some form can simply skip directly from IPv4-only to IPv6-mostly without having to worry about the costs of dual-stack at all.
