I don't see it. If I wanted to do compiler behavior tests I'd either not
use qmake or use a more specific command like:

QMAKE_CXXFLAGS += -std=c++11

(in full knowledge of the risks of course...)

Both feel kind of wrong to me:

CONFIG += c++11 feels more like "give me at least C++ 11 or newer"

CONFIG -= c++14 feels like "give me whatever predates C++ 14, even if it
is C++ 98" or simply "I'm a hillbilly, disable those newfangled C++ 14
features!"
