The draft is short and well written. The security considerations is also brief, but I agree with its basic point "This memo presents some requirements for future development, but does not specify anything." The persistent "visual confusability" consideration wrt internationalized domain names is duly noted as a consideration. In my opinion, the security considerations as written is appropriate and sufficient; other DNSSD WG protocol-focused drafts have more extensive security considerations and it is better to grind the security axe against those documents rather than here.
