As an editor I want to exclude certain pages from Special:UnconnectedPages on the client wiki in order to have a useful remaining backlog of pages that should be connected to a Wikidata Item via a sitelink.
**Problem:**
Currently Special:UnconnectedPages lists a lot of pages that should not have a Wikidata Item, thereby making the page less useful as a maintenance report.
**Example:**
[[https://en.wikipedia.org/wiki/Wikipedia:Redirects_for_discussion/Log/2019_April_5|Wikipedia:Redirects for discussion/Log/2019 April 5]] doesn’t need a Wikidata item, but shows up on [[https://en.wikipedia.org/w/index.php?title=Special:UnconnectedPages&limit=1000&namespace=4|Special:UnconnectedPages]] (in top 1000 of Wikipedia namespace at the time of writing).
**BDD**
GIVEN a page that is not connected to any Wikidata Item
AND the page has a the magicword TBD in its wikitext
THEN that page does not show up on Special:UnconnectedPages
**Acceptance criteria:**
[ ] A switch magic word is created to exclude a page from Special:UnconnectedPages
[ ] The query behind Special:UnconnectedPages checks if the page is excluded
**Open questions:**
* Is `__EXPECT_UNCONNECTED_PAGE__` the best name for this magic word?
