The 5.8cm is reported to be a very nice lens, but I don't think the choice of that FL was because it gave a more normal perspective. It seems more to have have been a compromise based on building a good performing lens that cleared the mirror. Most manufacturers (Nikon anyway) seem to have worked to reducing the focal length as soon as they could do it without compromising quality.
I'd love to try one sometime, though am tending toward shorter FL's lately myself. Oh, and it certainly seems to fit the thread topic of good pre-ai Nikkors; there is lots of love for this lens, and it doesn't get much more pre-ai than that (on an F).
No, you're not off-topic. Minolta made their own glass and arguably led the industry in R&D in coatings during the 60s and 70s. No complaints about the optical quality of old Rokkor and Rokkor-X lenses.

Like this one, on a matching body. :)
