> just that it minimizes the attack surface

I stopped using multiple browser for exactly that purpose. It actually increases your attack surface. While compartmentalization of browsers helps somewhat against tracking you now have to keep all of them updated. RCE bug in one of them already compromises everything you have on your machine, so having multiple browsers just means the attacker can pick from a wider array of targets.

I meant the attack surface of browsing sessions. Yes I agree, having multiple browsers increases the attack surface of the device, which is why I try to minimize the amount of apps installed. But browsers are an exception.
