Any title that implies finality of the subject in some way, either literally or figuratively. Often this is done by putting words like "Last" or "Final" in the title. "The Last X" is one of perhaps the most common form of this.
Often overlaps with Last of His Kind.
Compare Title Requiem.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.

You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
