OK, so I can see that Nat and I may disagree about this one, but I've shipped 0.25.0 with the experimental support for SKIP and FOCUS 'Annotations', largely because I have suites of slow integration tests that I need to play with more or less interactively. I don't think that the scaffolding does the API any harm, but the type of the properties map (<Any, Any>) and the name of the type NodeBuilder may be subject to change. You shouldn't end up building a dependency on either unless you start writing your own post-build transforms
