Combining vector and raster editors makes some amount of sense since the raster editor had some vector capabilities anyway, but yeah, tossing in layout/desktop publishing feels kind of weird. It's a bit like combining a microwave oven and a blender.
No, I used to work in a newspaper and we were switching between text editing, graphic design and image processing tools for our work. This makes a lot of sense! That said, most magazines and newspapers have designated people to focus on each of these and the chances of one person having to shift between all three is a little narrow.
