Since I shoot up to 8x10 film, I see no reason to push the limits of what 35mm can realistically do. I think of 35mm more as my alter-ego, when I deliberately want poetic little grainy prints instead of big highly detailed ones. But I suspect it's more the advent of small 35mm cameras entering the realm of digital moving images which has fueled the drive for 36mm lenses of higher performance than ever before. Film makers are perfectly willing to go out and spend 40 or 90 thousand dollars for a lens if it gives them a distinct edge over the competition in a feature documentary film possibly taking a decade or more to make. But Hollywood cinematographers are known to seek out and adapt old funky lenses too, for sake of some special look. But once word gets out, suddenly those same old lenses jump 2,000% in asking price. Just the psychology of it. It doesn't necessarily have to make sense. Likewise, it Leica puts its official logo on a nail clipper, it would probably cost $400.
But cost is relative. There's a lens and mirror fabricator less than 5 miles from me that can make anything you wish, provided you have a NASA or NSA credit card. If you can afford to launch a Hubble or Webb space telescope, you can afford the lenses and mirrors which go with it. In terms of earth-bound or Naval applications, they've made some amazing optics too; but I wouldn't ask too many things about those, or the FBI might start looking at you. How about a sample shot clear across a 3-mile wide harbor so densely foggy that one couldn't see ten yards, but where the image came out so crisp that a man clear across the harbor was seen breaking into a car, identified, and arrested? Hint - state of the art "hybrid" optical medical microscopes sometimes use analogous technology; but that's only a partial hint. The full story they wouldn't know themselves - they just provide the special optics as specified. Spies have better opportunities elsewhere.
And you wouldn't want to hang the camera around you neck like a Leica. It was something like 1200 lbs, nice and stable, even at sea. I think the main intended application was for Coast Guard drug running surveillance.
