Upping an interface for no reason and not configuring it is a cardinal sin. With the default addrgenmode if eui64 it sticks a link-local address to the interface. That is not good, as NetworkManager would see an address configured, assume the interface is already configured and won't touch it iself and the interface might stay unconfigured until the end of the days.
