most important for the default out-of-the-box commands that we ship with jbpm is that they are simple, easy and predictable. keep in mind that you don't have to design the commands to support all use cases. users can easily inherit from your commands to customize and add more return values. there is always the tradeoff between covering more features and complexity. try to find a good balance there. the command return values can be changed but keep in mind the usability.
