Due to dramatic circumstances, it was partially locked and put in "maintenance mode" only, meaning it would no longer evolve (features speaking). Some of you may have heard that more than six years ago, Requests was working toward a major version, namely the V3. There was even a completed fundraiser with a substantial amount, around $30k. At the time, there was a plan to bring Async and HTTP/2 support (most notably). You'll guess that none of the exposed promises ever landed.
