**Background**:
Extension:CreateRedirect is a nice little extension that helps creates redirects:
https://www.mediawiki.org/wiki/Extension:RedirectManager
It might be a candidate for bundling or integration into core, but lacks some functionality, which we'll deal with here:
Wikipedia uses a variety of {{redirect templates}} to categorise its redirects:
https://en.wikipedia.org/wiki/Category:Redirect_templates
**Proposal**
In Extension:RedirectManager, it should be possible to add redirect templates (plural) to the redirect when creating it. Some pages might have more than one template on them, e.g. a plural redirect to a disambiguation page.
For that, you're going to need a curated list of all redirect templates, e.g. at [[MediaWiki:Redirect-template-definitions]], a drop-down and the ability to select more than one of them at once.
There is some overlap here with {T393673}.
