pornography is just for erotic material, doesn't have to be hardcore porn. A playboy magazine would qualify for the tag as well.
There's a lot of things in yaoi (object) that don't look like pornography to me. Since we use yaoi to refer to both sfw and nsfw works, there's a mix of both in the yaoi (object) tag. post #1502502, post #3924560, post #1147420.
I would argue all of those examples fall under pornography. If you look at the tag you'll find plenty of similar examples. Stuff like post #7416736, post #7390940, post #7355684, etc.
This tag is more about characters' interaction with pornography than the content itself, it's for generic indecent material.
