I've tried for years to figure out why I prefer to look at black and white photographs of many subjects. It finally dawned on me after watching the movie, "La Dolce Vita" for the millionth time.
Removing color removes a layer of implied reality from the art. When that layer is removed we get to look at the image or movie as more of a fiction or story and less as a documentation of reality.
The lack of color, and the beguiling interplay of tones, allows us to put aside our presumption of objectivity and dive into whatever visual narrative the artist wanted to present.
And if you are just buying photographic art as an investment you can buy black and white prints without the worry that some of the colors in a color print might clash with your couch or your decorator's choice of wall paint.....
Having realized all of this I now want all camera makers to concentrate on giving us better and more customizable black and white modes. Regardless of sensor size or quantity of megapixels.
Why would they not want to give us the opportunity to make better black and white photos?
I wouldn't cost much to add better profiles to most cameras on the market.
