[Solved... ish] Need to Somehow Enable Wikification in Plone 5

I'm assuming this is different from text/x-web-markdown right?
Reading the Wikipedia entry, would "Markdown Extra" be closer to wiki style text markdown than the current default included list?

Is there a reason it is disable? Security? Stability? Other?

@espenmn how is that enabled?

I see that I do have the file markdown_to_html.py in my /opt/plone/buildout-cache/eggs/Products.PortalTransforms-2.2.1-py2.7.egg/Products/PortalTransforms/transforms
