Per the parent task, we want to enable users to filter Special:RecentChanges for edits made to pages with no page watchers. This can be limited to edits where there were zero page watchers at the time of the edit for ease of implementation.
There are a number of comments in T20790 and T15063 about possible approaches - we would like to make a decision about which approach to take.
- How could we enable this functionality?
- Could there be any performance concerns with edit save time or loading RecentChanges as a result?
