uri-host will match more or less anything from localhost to google.com, including domains like lan to local

if the real host is considered to be sensitive information, a sender MAY replace it with a pseudonym

It is impossible though to differentiate, in the current grammar, whether local is a domain or a pseudonym. And the question is: "should/would you want that?"
