I'm not sure any of that is necessary for what we're talking about: locally-installed software that intends to be used by one or more public websites. For instance, my interaction with local LLMs involves 0 web browsers, and there's no reason facebook.com needs to make calls to my locally-running LLM. Running HTML/XML files in the browser should be easier, but at the moment it already has the issues you speak of. It might make sense, IMO, for browsers to allow requests to localhost from websites also running on localhost.
