I'm going to take the exact opposite approach. I actually do think this is necessary and there is a place for it in Nikon's lineup and in my gear bag.
There are times when I need/want the flexibility of a kit, but I don't want to carry a heavy load. My primary nature shooting kit is the Z9, Z8, 24-120, 100-400, and 4002.8TC... Top gear for what I do, but if I have to hike 5 miles or travel on a commuter plane, I need to start making choices.
In a second bag, I have my backup gear. This is what subs in when something goes down. My Z9 and 400TC took a few falls this year, and I had to send stuff into to be serviced. My back-up is the Z6III and 180-600. It's good stuff, but not the equal to my major kit. Yet, I confidently will sub both in when needed and use this kit for most of my aquatic excursions (kayak, canoe, catamaran, whale boats, etc..). I've been looking for a 24-120 type lens for my back-up kit, and one that I could handle on the water. When shooting on the water in a moving vessel or close to the water's surface, lighter is better. I've considered adding the 24-200, but the close-up capabilities of the 24-105 gives it the edge. Furthermore, if the lens falls in the ocean or becomes subject to salt spray I'm "only" out $500.
I'm pretty certain that I'll be pre-ordering this one.
