I'm not saying the Copper Golem is a full on replacement for the Tuff Golem, not at all, but at it's core the new Copper Golem chest sorting mechanic does give us the option of using them as a more watered down version of the Tuff Golem! They are perfectly able to take your stuff and walk around with it while still having that Golem flair to them, although you do need to put the item you want them to carry into the copper chest first.. I wonder if Copper Golems will still receive that feature where they turn into statues after oxidizing for too long, would be pretty awesome to have frozen Copper Golems continue to hold and display items in your base don't you think?
