While this is a valid concern I think the conclusion "no *new*
security vulnerabilities" is correct. If you today embed data on an
intranet in JavaScript I can create a page that loads that script in a
SCRIPT tag and steal the data.

Of course if this is implemented in UAs, it will encourage intranets
to publish JSONRequest services, so the situation may well get worse.

You missed the fact that every request in this proposal seems to be a
POST request. No UA or proxy should cache POST anyway.
