Other than the issues others have raised about mailing list vs. PRs from Git{Hub,Lab}, here is the information you need to send to the FSF in order to contribute >15LOC:
- [Did you copy any files or text written by someone else in these changes? Even if that material is free software, we need to know about it.]
- [Do you have an employer who might have a basis to claim to own your changes? Do you attend a school which might make such a claim?]
- [For the copyright registration, what country are you a citizen of?]
- [What year were you born?]
- [Please write your email address here.]
- [Please write your postal address here.]
I have several bugfixes and enhancements to various org-babel languages that I maintain for my local code, but I have no interest in jumping through copyright assignment hoops or sharing my age & mailing address to push them upstream.
