I am finding the latter to be correct here. The '-a' arg to shutdown strikes
me as not very useful, since the presence of a root login will circumvent
whatever is in /etc/shutdown.allow. It would seem to me that it is precisely
_when_ root is logged in that an inadvertant or unauthorized ctrlaltdel
reboot would be most unwelcome.

I suppose the moral of the story is, "Don't leave root logins unattended."
(But wouldn't it be simpler to have, as a possible line in
/etc/shutdown.allow, "none"?)
