This configuration option was needed to fix a design flaw: Skin autodiscovery made it so that MediaWiki automatically detected all skins from inside the $skins folder and made them available. That way it was impossible to activate those skins as they were activated automatically. You could only later hide them again - that is what this option was there for. With MediaWiki 1.23, skin autodiscovery got deprecated. Since MediaWiki 1.24, not only custom skins, but also core skins can be installed properly, finally making $wgSkipSkins superfluous.
