I know im early (and thats the plan), But blender 4.4 is coming out on March 18th (so far) and it looks like it may be a decent size of an update due to the release/re-work of the animation tools blender has. I think having cargo support for 4.4 close to release would be good.

Release schedule is here: https://projects.blender.org/blender/blender/milestone/24

Not trying to be pushy, Just puttin the info out there
