There was clearly never talk nor discussion of a port opening
prohibition. On the other hand, it's still a reasonable proposition that
users who run Apache, SSH, and NFS should know enough about their system
to set up any requisite security (neither of the three services are
gaping security holes by default).
As for Samba, CUPS in browse mode, and Rhythmbox -- these have no easy
nor obvious firewall policy that makes them more secure. As a
first-order approximation, one could limit inbound access to them to the
current network as given by the (ipaddr, netmask) tuple, but that's a
hack. Perhaps a useful hack, but not without detailed prior discussion
in spec form.
