But Spock's phrase clearly blames the technological primitiveness of the ships for the cruelty of the war they fought.
Spock: "As you may recall from your histories, this conflict was fought, by our standards today, with primitive atomic weapons and in primitive space vessels, which allowed no quarter, no captives. Nor was there even ship-to-ship visual communication."
If the motivation is
the nature of the conflict and the not the technology of the 22nd century spacecraft, what you get is this:
This conflict was fought with 22nd century atomic weapons
This conflict was fought with 22nd century space vessels
This conflict allowed no quarter,
This conflict allowed no captives.
This conflict allowed no ship-to-ship visual communication.
There is absolutely no reason a Starship/Warship constructed at the same general time period as the NX-01 would be technologically incapable of visual communications with anyone, the idea that the Warships were mass produced so incredible cheaply or rapidly that Earth/Starfleet would be "force" to leave out a portion of the communications equipment is absurd and unacceptable. Much more likely is that the nature of the conflict prevents communications from happening, also Earth ships might simply be under orders
not to communicate with the enemy ships.
If sensors detect a Romulan ship, you don't hail them, you destroy the ship and kill the crew. The military concept of "no quarter" means, among other things, you don't accept a offer of surrender, the crews of disabled enemy warships are just left behind, while you go looking for more targets.
There's no canon as to exactly how the Romulan war began, if the Romulans began the war by committed a act so egregious, so offensive, so horrifying, then the tactics suggested might be a expected response on the part of the Humans.
