Re: Updated editors. I assume we'll be getting the 2010 Wiki editor with Extension:CodeMirror for syntax highlighting as a replacement for the current Source Editor, since that seems the easiest approach (at least, it is when I set up local MediaWiki instances), and MediaWiki's VisualEditor and 2017 wikitext editor as a replacement for the current VE and it's source mode.

But what's going to happen to the Classic rich-text editor? I'm not going to miss it, but I'm certainly curious.
