User blog comment:KurwaAntics/Simplify requests to enable estensions/@comment-1929113-20170306063104

Certain extensions are able to be turned on through Special:WikiFeatures. The ones you have to request through Special:Contact are typically the ones that staff do not think should either be wildly available or want to ensure the wiki knows what they are doing before enabling.

Though feel free to send this into Special:Contact/feedback :)
