Improving dream recall isn't necessarily important for lucid dreaming -- I practiced lucid dreaming for some years without any explicit attention to it. I can imagine ways it would be helpful: analyzing your dreams will help you recognize when you are dreaming, plus there's not much point to a lucid dream if you don't remember it.
My fears are more on the opposite side of things; some people advocate lucid dreaming methods where you slip directly from wake to lucid dream, but this requires passing through some rather terrifying states of consciousness I can't bring myself to intentionally experience.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
