The Universal Edit Button code originally added a meta tag similar to the following: <link rel="alternate" type="application/x-wiki" title="Edit this page" href="/w/index.php?title=Furry_fandom&action=edit" /> A suggestion on the discussion page of the Universal Edit Button website (http://universaleditbutton.org/Talk:Add_The_Link#Linking_Scheme) led to the implementation of a duplicate meta tag to provide the same functionality in r42339, looking something like this: <link rel="edit" title="Edit this page" href="/w/index.php?title=Furry_fandom&action=edit" /> As $wgUniversalEditButton is on by default, these tags combined take up over 500 bytes in the head of every page rendered by MediaWiki when you have longer, non-English URLs like /w/index.php?title=%D0%92%D0%B8%D0%BA%D0%B8%D0%A4%D1%83%D1%80:%D0%98%D0%BD%D1%84%D0%BE%D1%80%D0%BC%D0%B0%D1%86%D0%B8%D0%BE%D0%BD%D0%BD%D1%8B%D0%B9_%D0%A4%D1%83%D1%80%D1%80%D0%B8-%D0%BF%D0%BE%D1%80%D1%82%D0%B0%D0%BB&action=edit. While the use of rel="edit" may actually be cleaner, the fact is it is even less of a standard than that supported by the Firefox plugin. If we're going to have one, it would be better to just pick one.
Back-compat.
