While I was doing upgrade for some wiki, I found that it has installed https://www.mediawiki.org/wiki/Extension:GoogleSiteVerification

That extension is unmaintained from 2014, and there is https://www.mediawiki.org/wiki/Extension:WikiSEO which is maintained and it has configuration parameter $wgGoogleSiteVerificationKey which is doing the exactly same thing.

Since repository isn't on hosted on Gerrit, extension isn't on translatewiki.net, that's why I haven't created this task in correct format for requesting repository archiving.
Only steps which has to be done are archiving page on MediaWiki.org and editing item on Wikidata.

As @Addshore is listed as a maintainer, before I do this, I'd like to hear from him what he thinks.

I've created this task for transparency reasons.
