isn't this kind of move generally to be avoided? (or at least not necessary)

Easiest way is to try and move something and see if linter complains. but std::move is needed here! only literally return a; doesn't need to be return std::move(a) but using the param as a parameter in any way the C++ compiler does not automatically move it
