As part of the 2023 Community Wishlist Survey proposal to Change information about the number of watchers on a page, the $wgWatchersMaxAge variable should be decreased to 2592000 (30 * 24 * 3600 = 30 days).
Additionally, the Number of page watchers who visited recent edits label on action=info should specify this time period — i.e. Number of page watchers who visited recent edits in the last X days
- $wgWatchersMaxAge is reduced from 15552000 (180 days) to 2592000 (30 days)
- action=info displays the time period computed from $wgWatchersMaxAge
