People do the funniest things with DNS. It's a pretty good key-value store, especially for read-heavy workloads. Maybe you update counters for "what clients in this OT environment are posting telemetry to this web server"? DNS wouldn't be a good choice for that, but Redis is. But maybe you

If you are an ISP/registry/DNS provider, it makes sense to separate authoritative zones for your clients' domains, for all those cases your client move their domains somewhere else without notifying you (hell, they do that too often), or to be able to prepare moving domains to your servers.
