Technically, it has the original source editor too, sans the toolbar that has all the nice buttons (though those could in theory be readded via user JS if you have access to it--I'm basing that off Wikipedia having a gadget to replicate the 2006 editor and my own use of my user JS to copy the functionality of the extended toolbar gadget from there to the wiki I admin). But! changing the preferences on a UCP wiki to disable VisualEditor locally can change your editor preference on non-UCP wikis to VisualEditor because the preferences pages are different.

I think they should keep the switch that lets the original source editor be used, but knowing them, they probably won't.
