The page description (via Wikibase, or the override described in T184000) should be visible in the page information so that editors can easily verify it.
Patches:
- https://gerrit.wikimedia.org/r/#/c/423244/ Refactor business logic in description API into helper class
- https://gerrit.wikimedia.org/r/#/c/423245/ Add local and central description to page info
(The first one also makes the description available for PHP code.)
