I'm talking about adding new features that are only available with newer 
compiler versions. Not about refactoring existing features so that people have 
to upgrade to keep up with what they already had. The case of QVariant is a 
bit special because it is a feature that used to exist, but was broken in many 
ways, even if people were depending on it.

But for other things, I'm not shy about it. People can't complain that they 
can't use features that didn't exist when they wrote their application.  If 
they want to use new features, it stands to reason they've just upgraded Qt. 
If they can do that, they should be able to upgrade their compiler and 
toolchain too.
