[concurrency-interest] curious if there is a Local.java in the works for CompletableFutures like scala has

Why would someone want to rely on state they cannot control?

Is the idea to subvert some API that does not provide a way to pass state? This is strange especially in the context of Scala, where you can easily form tuples.
