Many worlds being true increases the likelihood that anthropic analysis can provide us with useful information about the type of existential risk we face. For example, if civilizations such as ours are commonplace, the Fermi paradox makes it likely that we will face some kind of great filter that usually destroys civilizations such as ours. If civilizations such as ours are rare, the odds of us facing such a great filter are much lower. Many worlds being true, I think, means we should increase our estimate of living in a universe in which we are common.
