This true in particular with thin walled soft aluminum rims such as old superlight Martano's from the 70s for which the rim would start to yield at approx 50 KGF.

The thing that stands out to me in the OPs post is the 110 KGF for a 36h symmetrical front. The Kinlin rim in question is a superlight using Kinlin's alternate material that enables high strength in a thin wall. (xKeyMet catalog as opposed to their Standard catalog that uses the standard alloy. They have TWO lines of rims, not one.)

A Kinlin isn't a '70s rim. If the rim was "yielding" at the spoke holes enough to change the tension of the spokes, they would have to bulge in a conspicuous way without cracking.

I doubt that it possible with a rim of that shape and hardness. There is a world of difference between the formed sheet rims of earlier eras and the extruded rimes we used now. The old rims were extremely flexible and couldn't have been used with 20 or 24 spokes.
