It does not bother you that when adding a feature macro one needs to 
remember to add it to all compiler configurations, live or dead? And that if 
one forgets nobody is any the wiser?

It does not bother you that we can't just add

#if defined(__cpp_foo) && __cpp_foo >= 201400
# define BOOST_CXX14_FOO
#endif

in one place and have it mostly work, instead of touching O(N) files?
