Technical debt/Unused config

This page reports unused configuration variables in wmf-config, as generated by wmf-config-wg-vars.mjs in mediawiki/tools/code-utils.git.

Prior iterations:

1. Aug 2018–Jan 2019
2. Jan—Feb 2019
3. Aug–Sep 2022

Reminder

Please do not propose mass removal via a configuration patch without involving relevant code owners. These results represent very low priority technical debt that does no harm to remain.

It serves as a useful prompt and reminder to review an extension's configuration values, an opportunity to on-board team mates or otherwise exercise and familiarise oneself with maintenance duties.

Issues to consider:

• The unused variable may be indicative of an incomplete migration, e.g. perhaps some other variable needs to be added to replace it, or some database migration has yet to be run.
• The variable may be defined with a typo/spelling mistake and actually needs to be corrected instead of removed.
• The query to Codesearch may have missed actual usage, e.g via computed or concatenated strings passed to Config->get().
• It is not uncommon that we deploy technically-unused variables a few weeks ahead before an accompanying feature is deployed, to prevent errors during launch.
