User:Spike/Add a link on Special:RecentChanges to see last 180 days

A user reports at Community noticeboard visiting a variety of wikis to see if they are suitable for adopting or being declared dormant. The user wishes to review activity on that wiki, not the record of the wiki's creation on Meta. By default, Special:RecentChanges shows only recent changes in the past 30 days. There are links to go back an even shorter distance in time, but not to show a greater interval. On a relatively inactive wiki, Special:RecentChanges for 30 days might show no activity, but this doesn't necessarily prove anything. (Anyone can get this listing by appending  to the URL for Special:RecentChanges, but this is tedious.)

Proposal
Modify the default value of  on all wikis to add to the form in Special:RecentChanges a link for a listing spanning 180 days, as shown.

The proposal includes no policy change that would prevent a wiki's bureaucrats from using Special:ManageWiki/settings to specify their own value of, including to reverse the change made by this proposal.
