The difference is that for images almost everything is done with raster graphics, vector is the niche exception. And for most uses where it makes sense (e.g. a logo) you can easily convert a raster to SVG automatically generally without requiring any manual tweaking. If the argument is that "maximize immediate practical usefulness" is not something interesting, I would say it makes sense to say "I don't understand why this approach is pushed". Anyway.
