Clarify whether "host state" does nothing or is an alias of "hostname state"

↪︎ host state
↪︎ hostname state
...

I suppose this means that the same algorithm steps shall be run for "host state" as for "hostname state", but when I read the spec naively, it would appear as if nothing would happen in the "host state". Can you clarify?

It's to be read like a switch statement. Perhaps this ought to be clarified/explained in Infra.
