(And, yes, I certainly put myself in the latter category.) I, too, would like to hear if other resolver operators see this, and if possible to what extent they are seeing it, and if we're really lucky to hear at least a few names for which this is happening. The latter is not to name-and-shame, but instead to be able to talk to the authoritative operators about what their configuration is so that we can maybe guide others away from this path.

A percentage of responses would be great, as would the percentage of the authoritative servers doing this. And, yes, I totally get that I'm asking you to do work that you don't need to do because the customers aren't calling.
