I looked at the source code. ImmutableSet doesn't support adding adding or removing elements incrementally. You can make an ImmutableSet.Builder from an existing ImmutableSet of n elements and then make a batch of m updates from which it will construct a new ImmutableSet in O(n+m) time. It simply isn't a persistent data structure.
