I didn't quite see your point immediately, I thought you meant we don't need this method, but you meant why not do: default Subscription and(Subscription other) { return Subscription.combine(this, other); } I agree this would work, and I don't mind it either way, but calling `combine` does incur a bit more overhead (when called with only a list of 2). The reason I think `and` is a bit more efficient this way is that I think two variable captures vs a `List` with 2 elements will be slightly more efficient. Not that I thought about it that long when implementing it, I just wanted to avoid creating the varargs array, and then the `List` if it isn't strictly needed. ------------- PR Review Comment: https://git.openjdk.org/jfx/pull/1069#discussion_r1257543221
