You can't. If we allow you to specify the 'anonymous' user, you could
assign negative idwka rights to 'anonymous' on the volume-level ACL to
prevent system:anyuser write access. But there is no way to prevent
access for system:authuser.

Note: giving a negative ACL on, say, system:anyuser would prevent _any_
user from getting rights; that's not what we'd want.
Since system:anyuser represents all users, it seems to me we could
introduce a way to indicate anonymous users. Perhaps with a new
system group, system:anonusers which represents users that are
not authenticed?

At that point we would specify a volume level negative right,

Negative rights:
 system:anonusers idwka

Why do you need a group, as opposed to simply mapping 32766 to a name?

Yes, I suppose just a way to represent ANONYMOUSID (32766) would
work, but the system: prefix seems intuitive to me and more
consistent with system:anyuser and system:authuser.
