I don't want to see RedWarn, a fundamentally different tool that focuses on being an on-wiki tool, similar to Twinkle, be abandoned. In fact, RedWarn's growth should ideally be hand-in-hand with Teyora, despite the two projects being disconnected other than by common ancestry. This means that the two major areas for counter vandalism tools, on-wiki tools (RedWarn) and standalone (Teyora) are both catered for in a user friendly way by actively developed community tools.
RedWarn 16.1 has been the current version for nearly over a year. If the RedWarn team does not increase development speed or seek financial or volunteering support, my concern is that the risk of the tool being abandoned is substantial. Therefore, forking RedWarn's TypeScript rewrite may be a consideration if resources allow. This will not effect any license agreements currently in place.
