Leitz have published some of the glass types for some of their lenses e.g. in the quarterly magazine they used to send to every one who registered a passport, including a set of Elmars glasses, but Elmars have gone through lots of sets. This is hardly 'only a few' people. Elmars are thin lens triplets like Tessars and the computer software will indeed converge to either design. given minimal constraint, and you do need the computer to reduce the manufacturing cost to the minimum, manufacturing cost is profit, not performance, and profit is important _ expansive marketing statements can skirt around performance issues.

the pro D4 only does about 68 LPM at Nyquist, but that can be in the dark when you need a flashlight to see your nose... 35mm was never about quality.

the Nikon 5cm f/1.4 is a superb lens high resolution and low distortion it is an enhanced double Gauss - a near symmetric design ,and what ISO do the films have?

I thought it was an asymmetric triplet, (is three and even number?) and even at /5.6 it softens into the corners, the post '94 M Elmar is a much better performer, there are published MTF diagrams for both lenses. - but I suppose great is subjective marketing speak?

So Zeiss are marketing Leica LTM lenses as well as having Cosina manufacture most of their own ZM lenses, that does sound strange?
