I think that normally this is mostly a special case for registration and
login and such, and that the "normal" skins should still be
view-protected, that is, when the "unrestricted" right is supported, the
default configuration should have a "loginAndRegistrationSkin" tha is
used only by them and is unrestricted, and the rest should still have a
view-protected skin.
Note, I'm also having issues with the user's own profile behaving _too_
much unrestricted, where users are allowed to add comments to their own
page even before they have been give edit rights. This can be a huge
problem, as their own page is *usuall* where spammers put google rank
spam.

XWikiRightsServiceImpl list several categories of access rights: view,
edit, comment, delete, register, admin, programming. Each action is mapped
to one of these categories. For example, /viewrev/ is a 'view' action,
/propupdate/ is an 'edit' action.
Currently, the most permissive right is "view", but some actions need an
even more permissive right. For example, if the wiki requires
authentication for viewing, then the skin will not be displayed.
We should add a new access right class, "unrestricted", which cannot be
used in the Access Rights Editor, but is used internally to allow some
actions to always be executed, regardless of the access rights of the
user.
This raises some security issues, like what if the skin really shouldn't
be accessible? What if a plugin registers an unrestricted action, but
nothing should be unrestricted? For this, we can do the following:
- add an option in xwiki.cfg, 'security.allow_unrestricted', which can
disable unrestricted access; in this case 'unrestricted' behaves as
'view'.
- add an option in XWikiPreferences, which actions are allowed to behave
as unrestricted. Although some plugins by default register an action as
'unres', we can force this action to require 'view' rights.
We need to add this, a lot of users are complaining that the skin isn't
displayed, we just have to decide how do we secure this right.
