I'd pretty much agree if we were talking about functions that might be used in third-party code. But you can't mark a key binding as obsolete. And if we provide a replacement for vc-next-action in the form of vc-commit that simplifies usage and cuts on unused features such a "steal lock", is there a reason not to replace its binding in the same release where we introduce the new command? We might keep vc-next-action defined for the time being, if only to allow users to revert the binding, in case some people actually use the "steal lock" functionality.
