Those are good points. DS9's entire final arc could be considered the finale. After all, Rom and Leeta's arc is done prior to WYLB. It's a shame we don't see them in the finale. After all, a big finale like that should feature everyone it can in some way, shape or form--or at least it would be nice if it did. I don't think we saw Keiko or the O'Brien kids either, except in the flashbacks. So changed I'd have made would have been to include every character possible, even as a 2-second walk-by. Hell, I'd even have gone out of my way to show the guy who runs the Klingon restaurant. But that's just me.
