I also ran into this. charm proof will give a warning for a missing copyright file, but charm create does not create a boiler plate template.
Suggest to have charm create make a boilerplate copyright template that needs to be updated. charm proof can then flag, as a warning (so it fails review), if the copyright boilerplate has not been updated. Similar to what we do for the Readme.ex
