I have said so in the past and I will continue to say this: as long as we 
don't have a CI system which can verify the C++11 subset we are allowed to 
use, it's pointless to try to restrict the usage. We are humans and no 
compilers. Nobody can expect that we remember which calls are allowed and 
which not if we have C++14 compliant compilers.

To me the only relevant and allowed subset of C++ is the one which compiles on 
build.kde.org.
