For me personally, I'd love it. It would give me a true sense of real distance. I've never been a fan of near-instantaneous travel across the stars.
However, as a compromise for this, I think SC would need to allow for a much faster travel. If I wanted to go quickly to a planet, I could select that planet and engage a "hyper-cruise" mechanic that would throw me through the system and bring me out in orbit around the planet/station in a few seconds.
