The SimilarEditors extension may be affected by IP Masking (see parent task: T326869).
Since we are not currently developing the extension, we should un-deploy it for now, to avoid any confusing breakages.
If/when we return to it in the future, we should update it to work with temporary accounts.
What needs doing
- Search the mediawiki-config repo for references to similareditors
- Remove all config related to the SimilarEditors extension. (This will include QuickSurveys config.)
- Look through https://www.mediawiki.org/wiki/Writing_an_extension_for_deployment to work out what other steps should be taken (and add them to this list)
- Deploy the changes
