I'm sure these are things designers will learn. I'm not sure that they really separate a junior from a senior designer though. At least in product design when you hire a senior designer, you're hiring a set of beliefs about how software is designed and built. They should have pretty well-founded opinions on a variety of things. I wouldn't expect a junior designer to have formed those yet.
