If there is no external network, then the behaviour of programs such as ping, telnet, ssh are irrelevant. All are of limited use without a functioning network.



That isn't entirely true. Some programs use the loopback interface to
provide/use services locally.


Then it's the user's task to configure the system appropriately. I run a webserver. I can configure it to listen to any IP address I choose, including 127.0.0.1. I don't need any bogus network interfaces, IP addresses or host names misconfigure by the vendor.

I mentioned _those_ programs by name because they were mentioned in the email that attracted my attention. None of those require a (misconfigured) hostname to resolve to anything.

Better to allow the user to configure the system _properly_ and to have it fail if it's broken than to make it work with misconfiguration.
