If I visit /admin/logout/ while logged in as a user that doesn't have
admin/staff access, I'm redirected to /admin/ and then to /admin/login/,
*without* being logged out of my existing user. This feels like a bug, for
several reasons:
* If I don't have permission to access `/admin/logout/` for some reason,
shouldn't I get told that, not just redirected to a login screen and left
to guess?
* The

docstring for logout()] says "This should *not* assume the user is already
logged in.", which isn't quite the same as "should log you out regardless
of what user you are" but sorta hints in that direction to me
* The [https://docs.djangoproject.com/en/5.2/releases/4.1/#log-out-via-get

any caveats about "all your users need to be staff" (my instinct is the
recommendation should be `logout` not `admin:logout` regardless -- #36575

access; I'm mildly suspicious of the

@login_not_required decorator on `login`] but I don't know if that's
actually relevant.
