I think having both the "combine" / "of" method and this "and" method gives you a bit of flexibility. Sometimes you may already have a subscription, then calling: subscription = subscription.and(otherSubscription); ... is nicer than: subscription = Subscription.combine(subscription, otherSubscription); When creating a list of subscriptions, `Subscription::of` / `Subscription::combine` is going to be nicer than having to chain multiple `and` calls. ------------- PR Review Comment: https://git.openjdk.org/jfx/pull/1069#discussion_r1169369137
