Why not make different example categories? One category, which has the same policies as Qt itself, i.e. it compiles
with all the compilers Qt supports. Additionally a category, which uses all new stuff C++11 stuff. And perhaps an 
experimental cat, which is insane and requires C++2x <--- ok, slight exaggeration.
Then the cats could be disabled with  -no-compile-examples, -no-compile-examples-modern, -no-compile-examples-insane.

I was in several projects where I have been told: Don't use this feature, don't use that feature. Sometimes the reasons
where understandable, sometimes I had the feeling the reason was the project manager was stuck in 98 and did not understand
anything beyond that. 

Now it is not Qt's task to teach modern C++, but if examples using those new features help/convince other people to migrate,
it also helps Qt.
