Of course you do.

naming hierarchy.  wildcards.  RRs (TXT).

All of those are core DNS constructs and they need to be understood for 
the SPF spec, at the risk of otherwise misconfiguring or misapplying SPF.

Hold on.  Just a sec.  OK.  My head is now back together.  The 
profundity of the deep philosophical point took me by surprise.

And yet I think I agree with you, if the point is that any citations 
that are normative need to be cited as normative on a case-by-case 
basis, as appropriate to the document.

That said, one would hope that there are some fairly concrete guidelines 
for what qualifies. Otherwise it's all ad hoc-ery.
