Perhaps the point is that the Confederation IS a bit unimaginative when it comes to names, whilst the Federation isn't?
The point being the future of Trek has more words that inspire exploration, inquisitiveness, courage or honour than ways of wrecking your enemies.
But again, it wasn't the series writers who came up with a class name for the ship. It was STO. And I doubt STO were trying to channel the Confederacy groupthink, because they have come up with unimaginative names for Federation ships classes many times in the past.
