Camera manufacturers are businesses. They have to sell products and fuel demand, so "improved" specs and features are used to drive demand.
At the same time, there is decision fatigue - more does automatically mean "better". For one digital model, Leica removed the back screen. Most TLRs have fixed lenses. 120 type MF film capacity is very limited, depending on the camera's format. Uncoated lenses have all the imperfections that "better" lenses successfully removed.
But, just looking at Leica M prices (vintage and new), there seems to be a strong demand for simplicity. "Good enough" actually sounds (and feels) good; a neo-vintage SLR or RF from a good manufacturer, with a few battle scars, in 35mm or 120, minimal electronic support, maybe with a wide angle and a tele lens in addition to the standard lens, some rolls of widely-available "allround" film, a camera bag that does not scream "camera bag", and a day (or weekend) free of obligations, a lightweight vest or coat, weather with a bit of variants, a snack, and a cold beer or hot tea at the end of the session - all that is "enough" for me.
Maybe it's the flip side of a mid-life crisis - when handling one of my V-Series cameras (or my R5), I often say to myself "thank you, world, that I am allowed to own these wonderful toys, thank you, that I am healthy and live in a country where there is peace, thank you, that I have not wiped out my brain completely but am still able to make plans, to see beauty in people and things, to appreciate all this around me."
