Not everyone can get into the mod files and change the power of the machine. I think it's better to leave the traditional methods of manipulating the parameters of the machines. Since a barrel is filled or an empty barrel fits the concept of a finished product, I think it's better to leave the possibility of the influence of speed and efficiency modules and beacons.
In addition, I can say that there are different mods that can affect your machines too, and a situation is created where modules will be needed.
