Spaghetti faucets: I've yet to hear a good answer to why anyone would want one

I notice that the execrable new construction at 25 Dialstone Lane has one of those spaghetti faucets installed above the range. The purpose for these, I’m told, is to spare the happy chef the onerous task of filling up a large pot of cold water at the sink and lugging it over to the cooktop. Swell, but that’s cold water the cook would have been lugging; these faucets never have a drain nearby, so she’s still faced with the task of returning that same pot of water to the sink, only now it will be filled with boiling liquid, not cold. What’s been gained at the expense of running a waterline here and adding an expensive fixture?

According to Better Homes and Garden, this is a “must-have” feature, but I remain unconvinced:

What Is a Pot Filler? Why It's a Must-Have Upgrade

A pot filler will transform your kitchen with its convenience and impressive design.

Really? How?
