[Development] QT_DEPRECATED_SINCE and retroactive deprecation

[Denis Shienkov]

Hi all.

Is it possible to add this "QT_DEPRECATED_SINCE" macro to the *cpp file 
if it was missed in there, but in the *h file it is exists?

For example, in some header file it is declared QT_DEPRECATED_SINCE(5,x) 
for the some foo() method..
So, can I add missed QT_DEPRECATED_SINCE(5,x) and to source file too? Or 
I need to wait up to Qt 5.6?

Is it belongs to "retroactive" deprecation or not (when in headers there 
are declared, but in sources there are missed)?

BR,
Denis
