This goes back to faction balance. KDF, including BCs, were designed for Hit and Run tactics. They need to be better vs the Feds in order to keep that tactic viable.
In the days before lockboxes and fleet vessels you might have had half a point. However, any niche that Fed snoozers may have once fit has been completely eroded by cross-faction/fleet ships that outclass them both at healing/protection (Wells, Recluse) and sustained damage or maneuverability (pretty much every Klinkydink snoozer). Even on a stat-by-stat basis Fed snoozers are terribly outclassed: the Fl. Vorcha has a frankly ridonkulous 1.1 mod to the Fleet Stargazer's .94, for instance).
