clever approach. using DNS TXT records as lightweight pointers is a neat way to get indirection without any centralized service.
the DNS-as-key-value-store angle is underrated. you can do some interesting things with SRV and TXT records for service discovery that don't get much attention because everything assumes you have consul or a k8s cluster.
does it handle TTL caching gracefully? that's the usual gotcha with DNS-based dynamic config โ if you update the TXT record you might be stale for a while depending on resolver config.
