Yes. Permissions are just objects in the page, if you are allowed to modify the
page then you are allowed to modify it's objects.
This makes logical sense because the worst you can do by modifying the permissions
on a page is to allow everyone to modify the page which you could have done anyway
by giving them your password.
Nobody has the power to deny adminstrators access to the page, the admin permission
on the space or wiki level trumps denial of permissions on the page level.

I recall that this option (in previous versions) was only available for
users who have admin rights, not for anyone.
Version 2.2.1.27354 and the one that is on playground, 2.3.28624, present
this issue.
