Why not just appreciate it for what it is, an interesting experiment merging historical photography elements with modern cameras. I don't see how a video like this garners such a negative response given it's running time. As a DP and editor myself I thought it was particularly interesting, but I also have an affinity for historical photography.
I don't think it's meant to be a workflow thing in this circumstance as much as it is an optical experiment to showcase some of the lens optics of yesterday and how they hold up with a high resolution image. Ultimately to gain appreciation for historical photography gear and to achieve a look what many social platforms are faking in their social streams.
I work with a vintage professional work flow personally, though not perfect for everything I do, it definitely has a place for certain clientele and facets of the industry.
