Frankly, I think there's nothing wrong with scene modes. Not to the point I'd feel affronted if they were on my camera. But. If you know what you're doing, and your camera, (like a K-7) has just the dials you can turn, you don't need em taking up space in your interface.
Meanwhile, it's just a bit of programming. Elementary stuff to anyone who knows photography. Personally, I don't think it matters much. But, if we're gonna have a spot on the dial being 'Green mode,' it wouldn't hurt to have the scene modes buried in a menu under there. Then you could hand the camera off to the kind of people you'd stick it in Green mode for, with the camera knowing more about what you'd like them to do, or just have another useful slot on the dial instead of one you don't use at all.
(My little Lumix would have both idiot mode and a menu-driven scene mode. The latter, I would leave set for 'snow' when I was back up north. This would usually mean I could expect the camera to do competent things when I couldn't really see the display.
(never set much store by automation, myself, but he's a clever little fellow. Still looking for a way to glue an eyecup on there, though.
)
My sweetie now uses that camera a lot and I can just phone in what will probably work well, even from a long way away. So I'm not down on these modes. I think they may as well put them there. (Or at least go ahead and make it a 'USER' mode position that defaults to 'idiot mode' and can be configured as you like) Just that they aren't a big deal. Not for a camera like the K-7.
