Declined extensions (<1.31)
Those extensions which are not available and a brief reason.
 * AccessControl – doesn’t work on MediaWiki 1.29+, and also has privacy issues
 * BlueSpice – security risk
 * Configure – ManageWiki does the same thing, and the extension doesn’t work with latest versions of MediaWiki
 * ConfirmAccount – incompatible with CentralAuth
 * DeleteBatch – because of technical limitations, see T956
 * DNSlookup – invades user privacy
 * DynamicPageList – flagged as unmaintained
 * EditAccount – incompatible with CentralAuth
 * EditUser – incompatible with CentralAuth and also flagged as unstable. Similar reasons to EditAccount.
 * EmbedAnything – security risk
 * EmbedVideo – security risk
 * External Data – security risk (SQL injection)
 * ExternalLinks – security risk, see T1555
 * Html2Wiki - unreadable code, see T2740
 * Html5mediator – declined due to security issues (arbitrary JS insertion), T1640. Use Widget:Html5media instead.
 * Markdown – flagged as unmaintained
 * MiniInvite – security risk
 * MultiUpload – flagged as unmaintained, instead use MsUpload
 * SecurePoll – reveals private information
 * Semantic MediaWiki – alters MediaWiki too much, use Cargo instead
 * Semantic Text Annotator – requires Semantic MediaWiki
 * Site settings – ManageWiki does the same thing
 * Tasks Extension – flagged as unstable
 * UploadWizard – Extension is too specific for Wikimedia. Unsuitable for independent wikis to be using it.
 * UserGroups – ManageWikiPermissions does the same thing.
 * UserMerge – incompatible with CentralAuth
 * WikiBanner – we don't accept ads
 * Extensions made by Wikia that do have pages on mediawiki.org – extensions such as Special:Withoutimages, MediaWiki:ImportJS, and Special:AdminDashboard are too specific for Wikia. Use similar extensions instead.

Disclaimer

 * Extensions not used by Miraheze or Wikimedia Foundation (a organization we trust to do rigorous security review) must pass security review by our volunteers. It may take long time to process.
 * Some extensions enabled by default cannot be disabled by local wikis or communities, nor can some extensions be used or managed by local wiki bureaucrats or administrators. Extensions in the first list that have a * next to them indicate that either they are required and cannot be disabled, and/or they cannot be used except by global Miraheze staff members. For example, CentralAuth is required, otherwise parts of Miraheze may break. CheckUser, GlobalBlocking, and RenameUser cannot be used except by Miraheze staff.
