Ah, the old referree problem. A breed that all too often feel their set of "rules" is the only set that matters.
Yes, I, too, view slides as a "different media" than color or B&W negatives, notwithstanding the obvious parallels and overlaps. Slides, as you say, Søren, is a "nail it, or bail it" sort of media, requiring a tighter set of disciplines. There is no "I can compensate for that in printing" option.
But, one can also approach negative materials with the same level of discipline. In fact, I often express the opinion (or, rant, depending on one's perspective) that negative materials have
no "latitude" - there is only one proper exposure (and pre-planned development) to nail the shot. Anything else, exposure-wise, is a compromise that makes the final image less than it could have been, just as with a slide.
The whole issue, I think, is to consider the requirements of the intended presentation method - how the film is going to be used. Understanding those requirements will enable one to adjust shooting techniques appropriate to that presentation method. If intended for projection only, for example, one can take full advantage of the dynamic range of the slide film. In contrast, if the slide is to be scanned and printed in a magazine, you need to style the image and adjust the lighting ratios such that it will print well - typically keeping the lighting ratio to about 4 stops.
