That was my first thought too, but it's wrong. The right thing is to
look at the strictness of the input function, because that is the API
we have defined to determine whether a datatype might possibly be
interested in rejecting nulls. The fact that domain_in() is the only
example in the core system doesn't make it correct to restrict the
functionality to domains.
