It's not commercial interest as much as very high cost. It's a huge amount of work to convert to IPv6, which includes: - almost all networking hardware in facilities, pops, switching centers, and on customer premises (basically every device in every home.) - almost all related software stacks like kernels, network control stacks, etc. - redesign and planning of addressing topologies, ranges, configuration, etc. - updates to all support systems: inventory databases, monitoring systems, provisioning systems, security systems, etc. - updates to tooling, documentation, UIs used by engineers, customer service, field techs. As you can see, it's a shit load of work for most large organizations and service providers.
