Please note I said that I *think* it should work, not that it does work. Could
you give it a try and see if it makes your life easier?
Now, looking at the code, I don't think it does work. I thought that
QCborValue::operator[] returned QCborValueRefs, but it doesn't. Adding a set
of non-const overloads returning QCborValueRef might be the trick. And it's a
trick we can add to QJsonValue too.
Converting from JSON is lossless and converting that content back to JSON is
lossless too. It's just not particularly efficient today.
