I care about it. I'm a sculptor just finishing up my BFA, so these things are really apparent to me. Visually, the ships from the original trilogy were impressive. They had variety of form, unity, and contrast. The whole shebang. They looked good, and you could tell the people who designed those ships had talent. Many of the EU ships don't have that feeling of excellence. They're either rushed-looking or just plain unremarkable. Same problem with many of the prequel ships. It's like all the talent evaporated and Star Wars just became a money making machine. There are exceptions, of course, but the original ships were good.
The nitpicking about the form of the ships is the difference between making a visually-mediocre game and game that is visually excellent.
p.s. The differences between the two nebulaB versions is pretty huge.
