In addition, 50+ mm lenses would mount with the rear element in front of the moving mirror without the need for "retro" focus optical designs.

I think the reason they went to 58/55/50 was that these focal lengths typically gave a FINDER magnification of 1 (100%).
If they used a 43mm lens on an SLR, the image is smaller than %100 on most SLRs.
FWIW, Using 43.27mm as "normal" yeilds a 85mm as very close to 2X and 135 as fairly close to 3X.
