It's not just precedent, it's about the nature of potential interactions between sentient races/species. Any non-violent engagement betwen alien star nations, whether on terms of equality or submission, would also require development of protocols and a bias against third parties who disrupt the arrangement.
The mechanics of the relationship and diplomatic systems in the game pre-suppose some interstellar diplomatic norms along these lines and concepts of an appropriate war - this happens to align with concepts from Terran history, but other species might have even more formalized protocols (or laws) of war and peace.
One could of course assume a galaxy where weakness is despised and strength contested in a relentless permanent war of one against all or all against all, but that is rather two-dimensional and less fun beyond the military dimension. The players of this game being of human origin, they'll want some opportunity to make deals and thus engage in diplomacy.
I agree. But I also think the game already accounts for that. If you have a game that is 8 Boskaran Empires, 2 Sluken Empires, and 3 Human Empires, it's going to be a very atypical place.
