But the purpose of doing that is to provide a suggestion for a change in approach for a given patch. I don't think it would make much sense to start a new thread because you lose the association between the original approach and the modified approach. That said, I haven't seen this particular feature used in the years I've followed the git mailing list, so perhaps it's not commonly used.
