Were these necessary given that we already had the OBSOLETE file in them? These extensions now cannot be downloaded with Special:ExtensionDistributor, and all old links pointing to SVN locations stopped working (e.g. links on mw.org). I think there are still plenty of people out there that might have older MediaWiki installs and might want these or other obsolete extensions.
