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/will eventually do the same thing, and 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
 * Html5mediator – declined due to security issues (arbitrary JS insertion), T1640. Use Widget:Html5media instead.
 * 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/will eventually do the same thing
 * Tasks Extension – flagged as unstable
 * UploadWizard – Extension is too specific for Wikimedia. Unsuitable for independent wikis to be using it.
 * UserGroups – gives users the ability to alter user rights (incl. checkusers) beyond recognition, see . This feature will soon be available with ManageWiki.
 * 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

 * Some extensions enabled by default cannot be managed/used by individual local communities at this time. These include CheckUser, RenameUser and GlobalBlocking (which are currently limited to global Stewards) and some extensions only have a function on Meta such as CreateWiki.
 * 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.
