The FSF advise that the authors be listed and "if several people helped
write the code, use all their names"[1]

My understanding is that there are some scenarios where it matters in a
lawsuit. Additionally, I am not positive that you can distribute without
listing the authors.

For my code I have a Contributing.md file that states the license and if you
want to be added to the credits list for that file, include that in your
pull request or in a separate pull request.
