Of course, that is also subjective.
Sure, you can see it that way, but a few years ago, for example, ice cube dispensers or steam ovens were decadent, today they are common.
But if someone doesn't even want to empty their dishwasher anymore, that's already going in that direction.
That wouldn't be the argument for me either. But when I notice that the two of us as almost "daily cooks" sometimes have the problem that everything doesn't fit in at once (larger pots or the like), then I can very well imagine that with 3 kids here, there is a justified existence of a second device.
probably more of a crazy idea.
I don't see it that way, it's worth a discussion
I already wrote in the first post, if the kitchen planning allows it easily, why not? Here in the neighborhood, the household's second car stands 90% of the time in the driveway instead of being used, but no one sees that as decadent.
