... I once needed to implement a very simple DNS forwarder in an unusual context where supporting UDP was tricky. In that case, we decided on exactly this behavior: always return a trivial TC=1 to force DNS over TCP. It worked fine. I’ve also occasionally needed to implement TCP-only DNS stub behaviors, for similar reasons. Having some documentation about this option might be helpful guidance for future DNS implementors in situations where simplicity is more important than performance. Ben, I agree. I think this is a practical distillation of what I wanted to see in the first place, just scoped to actions for implementors rather than document authors. Would you be interested in coauthoring such a draft? Not for 123, but after. Sure, I would be happy to help with that! —Ben
