The motivation would be to avoid having to write conditionals in an assets loop.
There's also one case where I've found it a bit of a pain, when you want to pick a single random photo.
The code below is nice, clean and efficient until you want to restrict the image by a property of some field (e.g. hide_from_gallery = false), at which point you have to start looping through them all...
Don't know how hard this is to do.
