Compatibility Usage is not designed to model every possible CLI. It's generally designed for CLIs that follow standard GNU-style options. While it is not high priority, adding support for CLIs that differ from the standard may be allowed. As an example, some CLIs may accept multiple options on a flag: --flag option1 option2. This is poor design as it's unclear to the user if "option2" is another positional arg or not. What we will likely do for behaviors like this is allow it, but show a warning that it is not recommended.
