Submitting a package on another's behalf

[Steven vanZyl]

Hello!

I would like to submit a package to Guix that someone I know wrote.
They do not wish to submit it themselves, and have given me explicit
permission to do so on their behalf.

I was wondering if there were any special considerations to be made? I
have added both their and my names to the copyright of the file in
question, and I was going to mark them as Co-author on the Git commit.
Is there anything else I should do?
