I'd document that for now functions are always replaced (you might need to update your impl to make this work). In theory there should not be too many functions anyway, and updating functions does not have impact on the current rule matches. So in the release notes, and documentation when you do it. 1) functions are always replaced, as no binary diff at the moment 2) type declarations can be dynamically added, but cannot be modified or removed at the moment (any volunteers to make this work?).
