Same principle applies to, e.g., Leica cameras. Yes, they're pricey (absurdly so), but the lack of features, the slow speed, and the lack of configuration contributes to me improving my photography. It doesn't make me a better photographer, but it gives me the time and space to focus on being one, rather than just firehosing my camera at whatever is in front of me. It makes my photography intentional rather than reactive.
