I think the assumption that near-infinity horizons are acceptable for lens evaluation is an obsolete carry-over of the [bad] old days of film.

IIRC, A.A. relied on testing with trees on the horizon, and what I think he described as "infinite detail the closer you looked".

In terms of cycles per picture height, an 8x10 view camera with film in it is nothing to sneeze at, even by today's standards. Such negatives are sufficiently sharp that there is a clear difference between an 8x10 silver-gelatin contact print on F paper and an identically sized print made in an enlarger.
