VE (which is "still experimental" for outside Wikimedia, as I read)
Correct. The Foundation's budget priorities don't align with us making the epic re-engineering of VE into a state that it's as easy to install as the rest of the MediaWiki, and so it would be irresponsible for us to recommend it to low-end third party users.
Note that there's no-one who is paid by the Foundation to provide support to anyone for any part of MediaWiki, core or extensions, let alone VE. The support that do people get is generally either staff working in their personal time, or other members of our wonderful developer community, both volunteers and those paid by other organisations.
To help the team out, I have updated the three old status systems to explain to people that the are obsolete , noted that there aren't any VE-specific engineering update systems any more , and removed the reference to when the 2017 editor's integration last changed . Thanks for spotting the issues, and sorry it caused you concern!
