Ron, stop it. It's a condition that is known to impede sprinkler operation. Doesn't matter if the AHJ prescribed it - which they very well may have not. Most of these installations were by lazy contractors trying to shorten drops in future TI work. Some cultures still use human teeth for currency, but that doesn't make it right. As the AHJ's like to say, "Just because we did it wrong before doesn't make it right now."

I keep going back in my mind to the tech that pointed out a coverage deficiency in coverage that he saw in one part of the building, and called out as such within the test reports themselves, rather than as comments, but missed a similar deficiency elsewhere. After the building burnt due to the deficiency that he missed the lawyer convinced the jury that the tech was practicing engineering without a license, that the owner had a perfect right to expect that a complete engineering review had been done as the tech acted like an engineer and made at least one engineering call. End result was a $12M judgement over a couple hundred dollar inspection. I think George told us all about this originally. And this is merely the worst case. Heat collectors, old or new are, are a design/layout issue and so allowed or denied by the AHJ. The owner needs to be informed of the questionability of the efficacy, and perhaps the AHJ directly, dependent on the rules regarding reporting within the jurisdiction, but hey are not something that a tech can decide need to be/should be there or not.
