As discussed at bug 5685 [[Special:CheckUser]] is a regular restricted special page. But access by an user without CheckUser rights results in a "No such special page" instead of a "Permission error". This is illogical and inconsistent. See r15994 and r15997 for the output of suggest groups with the needed permissions.
I completely agree. The reason mentioned in Bug 5685 for "hiding" this extension is that users don't like it. Well, maybe they also don't like the deletion function, the block function, etc. This extension is well-documented, and many wikis may discuss about adding users with check user access. I don't think that we should hide this extension at all. If a user wants to know about this feature, he knows. It's not hidden – and it's also shown in Special:Listusers. *People should know about the structure of wiki.* They should know that their IP address can be obtained if they do wrong things. *They probably already know that* from the documentation and the discussions about the extension. The hiding of the extension is completely unsensible.
