The limitations of C++11 shouldn't really be relevant today.
Source: Someone who was, until recently, limited to C++03. Luckily we're up to 17 now, but occasionally 11 limitations creep in.
In any case, I revised that section to explain how even the "fixed" version in C++14 is still a paper-cut, and make the section hopefully flow a little better.
ETA: I replied to the right comment. I'm agreeing with you :-)
I was just saying that being stuck on older versions is more common that most people think.
