Au contraire, my little petit choux.
First of all, it's the Archive's contention that no story, no matter how short / throwaway / fluffy / whatever isn't good enough to be uploaded there. Although authors have been known to disagree with this premise. (They are, of course, wrong.

)
Secondly, Kerth ads have previously been submitted. I'm thinking by Artemis, although could be wrong there.
And, thirdly, I'd been thinking the same thing and was just about to post suggesting you send them along.
