The only issue I have ran into is that some of these newer features are not yet available in compilers that are shipping with OS's we are deploying on, so I HAVE to continue writing to C++98 since installing a new compiler/libraries is a no go (if it is not vendor supported, can't do it, thank you US gov't rules!). It will take some time for the compilers and their libc++ libraries to move forward and have older versions of OS's replaced by ones that do support it. That being said, wherever I can (in personal projects) I will slowly start adapting and using the new features...
