Skipping them feels a bit weird to me as objectaddress.c acts as an
interface to make a bit readable catalog dependencies. It's true that
we are in a weird spot in this representation due to the way these two
properties are stored in the catalogs, but if we can make the text
presented to the reader less confusing that seems like a benefit to
me. You have much more context than myself here, of course, so
perhaps my impression is wrong.
