If the point is to track the changes made by ECMA-404 that decision has been made for us (see end of section 4 in 404).
(Note also that JSON is whitespace-tolerant today, so not having that for the new non-containers at top-levels but everywhere else would be rather surprising.*)

Minimal change appears to be:

JSON-text = ws value ws

Gre, Carsten

*) The other interesting practical usage here is removing newlines from the allowed whitespace for a single JSON-text and joining sequences of these by newlines to form streams of JSON values.
But that is outside the scope of application/json and application/__+json, an instance of which is exactly one JSON-text.
(truenull3true is a valid stream of JSON texts if you dont require adding whitespace as delimiters.
Implementations that employ a typical form of tokenization without knowing what those tokens can be in JSON wont like that.  In any case, whitespace is needed to separate numbers.)
