We started supporting C++98 during the course of Qt 4.x.
We dropped MSVC 6, in Qt 4.5 (despite there was still people using it) and
were able to finally use member template functions for example and deprecate
qObjectFind and such.
I don't see why we could not force C++11 during Qt 5.x lifetime.
Remember that Qt 6 is in the very far future if it is going to ever exist.
Qt 5 is there to stay a long time.
At some point we are going to drop MSVC 2008 and GCC 4.4
The question is when.
And to answer this question we can use the facts such as how many people are
still needing it. Is supporting those worth the burden.

True, you should not get -1 for that.
