The scan is the least of the problems - good luck getting to that level of detail with mostly vintage lenses, balancing depth of field and diffraction, keeping the film perfectly flat, on a stable enough tripod with no vibration whatsoever; developing perfectly in the dedicated developer. Yes, it's impressive but no, it's not relevant to the average user or hobbyist.

I wonder how this compares to Technical Pan, which I imagine it was modeled after.

500 megapixels can have less detail than an old 1 mpix digital from 2001.

[Image resolution is a very complicated topic](https://en.wikipedia.org/wiki/Image_resolution) and megapixel count, or even lines/mm does not tell the full story.
