As far as I can tell, the target market for steaming hot water taps is office kitchens.
When a kitchen serves 100+ people things like limescale will inevitably be a problem. If the steaming hot water tap is plumbed in, with replaceable water filters and a regular service contract - that's an advantage, not a disadvantage.
Steaming hot water taps can supply lots of hot water fast, so even if a load of people are making drinks at the same time in between meetings, they can keep up.
There's also a safety argument that if you've got a kettle and a mug, that's two things of boiling water you could drop, and eliminating one of the two makes things safer. And because the steaming hot water tap is directly above a drain, the impact of a spill is much reduced. And a lot of these taps make water that is steaming but somewhat below boiling, which might be safer or something?

Not sure why you'd want one for home though.
