Unsure of the direction of reasoning here. The 1010/1 ends set is shown in catalogue nr. 12 of 1953 on page 19. It still appears in catalogue nr. 18 of 1985, on page 34. Do not see its presence or absence as much of a trend/fashion point.

Those Campagnolo 1010/1's I would call semi-forged. Coined, the edges on both side show a semi radius. They are of thinner material than the ubiquitous Campagnolo forged design. No room for an adjuster screw. My guess would be 4mm thick from memory. About the same as the vertical dropouts. On those often the top builders brazed on a washer to the inside of the axle slot end. It provided more room and clamping dimension, the axle was less likely to overextend and interfere with the skewer.
