I'll post this again. Does this camera not already meet one of your two primary characteristics?
Fujfilm announces XP170 waterproof compact with wireless image transfer
If you simply tape an opaque cover over the LCD, this camera satisfies both of the characteristics you stipulated.
All of the benefits you listed above apply. The only time you'd have to lift the cover is to change a setting that is only accessible via a menu setting.
I doubt any manufacturer will eliminate the LCD screen any time soon, but the XP170 (and similar WIFI enabled cameras) enable the working style you described.
It's here. You can do it now.
Taping the LCD is not an option.
That's just silly, might as well use it if it's there.
Think about this from manufacturing perspective.
Instead of fighting with thousands other companies for expensive OLED/MOLED/WhateverLED, you'd be introducing a brand new camera style that street-photography ninjas would love.
Heck, I'm not a street photographer and I like the idea 😀
