Come on'n get your jamaharon on! There are no real rules—just don't break the weather control network.
But season 7 was the last season of TNG. DS9 was busy with other things and Voyager was elsewhere.
The Ferengi from "The Price" showed up in VOY, as did the Borg Queen, and Tom Riker was pivotal to an episode of DS9.

Why would Starfleet be so fundamentally uninterested in learning about an enitity literally birthed by one of their Starships?
