It’s quite interesting that a duplicate of the WTH gets more votes than the “original” idea. Maybe we should sum those points from both topics? 
IMO, much more annoying behavior is that it’s not refreshing template value by itself once you put what you wanted into this text area.
Anyways, I personally don’t think that removing this tutorial completely would be a good solution. At a still-learning stage it still could be helpful to take a peek on this example when needed.
Apart from that, there wouldn’t be much benefit after all. You would still need to focus on the text area and then hit CMD/CTRL + V to paste your template. So that would only eliminate CMD/CTRL + A step. Still not efficient enough. “Paste from clipboard” button would be much more useful and flexible.
