The basic question is simply this: is it sufficient to list the key

with that.  But let's at least have the debate based on facts.

It is in fact sufficient to list the key algorithm in the header.

Let us suppose for the sake of argument that the DNS contained an  
undifferentiated bag of bits. There is no plausible attack against  
that. You can't lie to someone and get them to get a false positive.  
Or to phrase that another way, if you could do it, then there's a Best  
Paper award waiting for you at the next CRYPTO and you'll be  
catapulted into the limelight for your crypto-fu. It would likely also  
be a new fundamental result in core mathematics, as well.
