Now that T228780: New user right for creation of new short URL has introduced a requirement for a user right (urlshortener-create-url) in order to create new short urls, $wgUrlShortenerReadOnly, which is currently used on wikimedia foundation wikis to restrict creation of short urls on non-meta wikis, can be deprecated in favor of the new right requirement.
- Remove the right from all (*) on all wikis
- Grant the right to * on meta wiki
- Remove uses of $wgUrlShortenerReadOnly
