I appreciate the support. But FWIW, I don't think Kalium was trolling. Although he (I assume, but correct me if I am wrong) and I disagree on the risk versus reward of extending the time-to-live of cached resolutions beyond the authoritative TTL, I nevertheless appreciated and enjoyed his feedback.
I'm afraid we're simply going to have to agree to disagree on this point. I do not share the opinion that this is a good idea with significant upside and virtually no downside. I also do not agree that none of the issues I have raised apply to the original suggestion - I believe they do apply, which is why I raised them.
