**To-do list**
- This task
-- [+] Add maintainers of that extension/skin as subscribers to this task (if they have no apparent Phabricator account, notify them on-wiki or via email if possible and note it here).
-- [+] Add Phabricator project #MachineVision as a tag for this task, and remove #mediawiki-extensions-other/#other-skins as appropriate.
