It hasn't. What changed is how G++ represents such types. The code is the same
in C++14 and C++17, i.e. there's an empty base class present in the source
code, not something introduced by the language. And there's no such thing as a
"hidden field" in any version of the C++ standard. C++17 didn't introduce
anything here.
