> The current asynchronous invocations allocate a new {{CompletableFuture}} instance (plus a {{UniHandle}}, and a {{ComposedAsyncInvocationStage}}) for every interceptor that calls {{compose()}} or the other {{InvocationState}} methods that add a callback.
> We can reduce this by having a list of handlers in each invocation stage, and only creating a new {{CompletableFuture}} when we need to change the {{command}}.
