I can't disagree more. Sistine chapel is a warmonger wonder. You push people back in land prewar, gives you the ability to attack 3-5 cities on the turn of DOW. This is a HUGE advantage, crippling the enemy from the beginning of the war, and shaving 5-ish turns off the war length. You can take a couple of cities with absolute minimal forces, and move in the longbows easily, move the attackers back over your own roads, ready to regroup to make 2-3 big stacks for the core. Culture is big for both culture AND domination. Very neglected feature of the game, and a neglected wonder. If I get a good shot, I always build it, unless I'm heading to space, then it's utterly useless. But don't neglect culture on a domination game. It matters a lot.
In my CIV history I'm primarily a domination game winner. I never have trouble and have only built the Sistine Chapel one time. If you have enough culture happening to push your enemy's borders back that much, perhaps you should consider shaving a ton of turns off your game and going cultural.
The advantage you discuss is nice, but not by any means necessary. Especially if you're looking at

I don't neglect culture on domination wins. I use the slider. No hammers invested, and once I'm on a solid domination push, I don't really need to focus on tech too much unless I've done something wrong. Also keeps my war weariness at bay.
