Followup on T146631
On https://wikimedia.biterg.io/app/kibana#/dashboard/Git-Demographics in "Last Attracted Developers", "First Commit Date" is not the date when the initial patch set revision was committed, but when the last patch set revision was committed.
This makes it unnecessarily hard to really get a list of the last new contributors and actively make sure that their patches get quick feedback.
