It changes the model of the world that resolvers _who implement this_ have. The draft calls all of that out explicitly, I think (early versions of the draft didn't adequately, I thought, but this one certainly does in my reading). A resolver that doesn't implement this stuff is unaffected. And what of a resolver that doesn't do this and which is querying another resolver that does? Well, of course, those cases hurt in other ways too; but also, that's part of the risk of deploying these tailored answers on the authoritative side anyway. I think that's out of scope for this document, though I'm certainly prepared to work on another doc that talks about these issues.
