Configuring plugin extensions - why deprecate arguments

[morvael]

I use jaxb2-maven-plugin with https://github.com/sabomichal/immutable-xjc that is configured via extra arguments. But I get this warning: "Parameter 'arguments' (user property 'xjc.arguments') is deprecated: This should be removed in the 2.0+ release, as all arguments should be handled by other parameters.". How to configure plugin extension when you'll remove this feature?
