@yojimbo Often, yes. But in the scope of my Blog post, that's just a prominent example. The conent is more about linux packet filters and firewall technologies in general. And there's many more potential use-cases for that.

@Larvitz You're not wrong; and an exposed ssh port has been ubiquitous for many yeahs, so it makes for a good example. These days I tend to argue the other way around - the host firewall should be involved in blocking outbound traffic as it's primary job. There's no need to block inbound traffic, as there should be no services on "unwanted" ports. Network-level firewalling is a different beast though.
