While reading and cleaning I saw that the default message for [[mw:MediaWiki:Accesskey-n-sitesupport]] has become a redlink. I was unable to find documentation to see that it had been deprecated or accidentally omitted, and searching the wiki itself was a dead loss.

Can someone please 1) enlighten me on the specific case, so I can delete relevant links; and 2) instruct me on how and where I should have looked to find this out for myself.

If nothing else, I would have thought that we could have a list of deprecated or removed components at MW to help the less skilled. Thanks.
