Keith Zantow built a sample (but legit) plugin for Jenkins world. I thought it may be worth investigating if this could be HOSTED as a real plugin, and then used as a binary dependency of the ATH run (ie not part of main blue ocean build).
This will act as a canary when some kind of extensibility breaks.
Keith Zantow is this a good idea or not? if you think it is, Ivan could make it happen (if you are able to open the hosting ticket and publish it).
