[Mediawiki-l] making a few SpecialPages restricted

[jidanni at jidanni.org]

On Special:Specialpages, Special:Import only shows up if one is a Sysop.
How do I make some others listed there act the same? E.g., Special:Ipblocklist.
Do I really have to perform open heart surgery,
http://www.mediawiki.org/wiki/Manual:Special_pages#Restricting_the_page_to_sysops_or_other_users_with_special_rights
or can I use $wgHooks['SpecialPage_initList'] in LocalSettings.php?
Must I use $wgUser->isAllowed('editinterface')?
