The point of the parent was to write C++ code the C++ way. Most arrays in real programs should be std::vector.

Imitating C arrays with std::array is the perfect example of bastardized C/C++ code.

Using std::array is writing code C++ way. If you know size of the array compile time and you know it will fit the stack then there is no reason to use std::vector.
