In the traditional home user scenario, it’s largely pointless, however as a premium feature to differentiate and cater for a prosumer who may use virtualisation/teaming/LACP and has a managed switch, it’s a cheap bullet point. It’s frustrating having to ‘waste’ a slot on additional ports unless you specifically need something non standard/exotic. Also the low end intel stuff can vary in terms of compatibility/capabilities under certain OS’ and the bigger the number doesn’t always tie in with additional features as you may expect.
