I don't know if it's overkill, but it doesn't look like a bike that is suitable for commuting, for the following reasons:
It looks fancy, so it will get stolen (a good commuter needs to run flawlessly but look like crap with lots of dust on it)
It is expensive, so when it gets stolen, you will cry
None of the required commuter bike accessories are present or even possible to install: lights, rear rack, etc.
Questionable handlebars.
Commuter bikes are all about practicality and safety in a somewhat hostile environment. Performance is good to have but secondary.
For example to ride in the city you need one finger on the brake at all times, as when you really need to do an emergency braking, the half second you need to move your hand to reach the front brake lever may be the difference between stopping safely and crashing. In addition the "racing style" handlebars force you into racing position when reaching for the brakes, which means you see less of your surroundings unless you bend your neck at an uncomfortable angle all the time. A typical commuter has a more upright position to be able to both have your finger on the brake and have your head high enough to see over parked cars at intersections.
Without a rear rack, you will need to use a backpack to carry your stuff, so you will arrive at work with your back drenched in sweat.
There are no mudguards, so if the road is wet you will also be sprayed with stuff of questionable cleanliness, and god forbid you stick a wheel in dog poo... If you care about weight, you can use plastic mudflaps, basically anything is better than nothing.
If you plan to use it at night more than once, you really need good lights. Even in full sunlight, when the sun is low and blinds drivers, lights are very useful. If a driver's windshield is a bit dirty and they get the sun in their face, and you're riding in the shadow of trees planted on the side of the road, the only thing they'll see is your rear blinkie.
Also for a commuter I like fatter tyres so if I have a choice between a nice small safe road with no cars but old asphalt of dubious quality, and the highway, I can ride on the bumpy road/path just fine. But the fat tyres are slower.
