Is there going to be multiple memory copies when Packet is constructed using std::string?

https://github.com/alephzero/alephzero/blob/6f81ec985724bad87b04fba44e2a664f272f67a7/src/packet.cpp#L85 The reason why the parameter of the constructor Packet::Packet(std::string payload) doesn't use const & or &&, and uses value passing, even if moving is performed, copying will still occur.
