This thread is quite old, but there are some news here that are relevant :

http://www.rfc-editor.org/rfc/rfc7493.txt

Basically, i think QJson is currently conform to i-json (interoperable 
json). That should at least :
- gives some arguments about *not* using 64bit integers (this is handled 
by the RFC : use strings in that case)
- maybe allows a strict / non strict mode.
