This applies to axioms as well, which are easy to overlook because they have no value to check the type against. Letting one through is not merely untidy: an axiom whose type is an arbitrary term inhabits whatever that term is later found definitionally equal to, and the eta and proof irrelevance rules are happy to equate a term like this with a great many things.
