When I look at a real scene with my real eyes, I do focus on specific features a few at a time, but am aware of the whole scene, and can choose to focus on any particular object in it as I want. So, when I look at a picture of a real scene, I also look at small parts containing specific features, but I notice when I cannot focus on some of those features like I could if I were looking at the real scene.
So, I want my photos to convey the entire experience of viewing the actual scene, as best as I can accomplish that.
That said, if I want to mimic a photo of a real scene taken "back in the day", I would try to get the depth of field in the modern photo to be approximately the same as the historical one I am mimicking. So, yes, back ground might be slightly soft focus for shots of subjects close to the camera. But, blurry images of posts and people's hats in front of a train I am photographing are not the types of historical photos I would choose to mimic.
