I have often relied on github metadata to identify immediately the RFC author. But this does not work without some amount of effort on the part of people maintaining the RFC repository to try to preserve author identification in the commits.
Should we add an Author: "Your Name here" <[email protected]> to the RFC header? (And I guess give people the option of deleting the line from their RFC draft if they do not want to be personally identified with the RFC forever, though I am not sure whether trying to accommodate that request makes sense...)
