The better way is to actually change such undocumented stuff unpredictably and automatically every release. Write a script to randomize the structure layout. Append random text to names. Don't document any of that, and don't keep the scripts to do so in the same repo. "This might change or break at any time" isn't nearly as good a deterrent as "This will change every release. Don't use it directly, use the public interface at <insert location>".
