The better option is to stop requiring copyright paperwork. It is harmful to the Emacs project.
Stefan is wrong. The annoyance of signing the paperwork is minor and the process is usually simple. When asked, contributors are ready to sign the papers, I cannot remember when I last heard someone say no (if I ever did).
We have more than 2500 people who signed the copyright assignment for Emacs (and many more for other core GNU projects).
