just asking but the difference bwetween `println(workflow.toYaml())`  adding a newline at the end of the file when piped into the yaml and `workflow.writeToFile()`  not doing so is not so important right?
.. we could make `writeToFile()`  add a newline too, just to make it more unified (also some editors show warnings on files without trailing linebreak) i guess its bad form to not have that..

for now i sneaked a `trainingNewline`  argument into my PR, but it would probably be better without ?

Yes, such changes in existing features are best done in separate PRs for visibility
