Generally, I think it would be a good goal for JEP-400 to not require any source-code changes to any use-sites, at least for this common idiom of wrapping a `PrintStream` in a `PrintWriter`.  While we may have the ability to change JDK use-sites, we do not have the ability to change any usages outside of JDK, and we should try not to break those usages in the way that the JDK tools have been broken.
