Unfortunately, yes, it is spoilery for all seven seasons. Same with another essay I wrote about Quark's role in the overall DS9 narrative, "Trickster and Wise Fool".
I do love the entire DS9 ensemble, too. (Maybe Dax, Quark, Garak and Bashir a little more than the rest, but still.) And they're amply featured in my DS9 fic; the one I'm proudest of is Quark's Day, which is set between episodes 6 and 7 of the sixth season and which features every single character (with Quark as the pov character interacting with them). There are some DS9/B5 and DS9/Farscape crossovers waiting for you, too, once you've watched more.
