My point was not so much "just use JSON". My point was "you are
disguising something that requires stateful parsing as a simple
key/value scheme, which is bound to lead to bugs eventually". I.e. if
someone were to write a parser that would (e.g.) just grep for a public
key, they'd end up with ambiguous results at best.
