Thanks @werick, we will keep you in the loop.
I don't see an issue with doing a new git repo - it has some advantages over branching.
Did we decide on using the existing Jira and Wiki? I noticed that there are about 50 unresolved issues for sync - doesn't necessarily mean we need a new project, we can just use the version fields to keep track of that.
If we are using the existing sync wiki, I can start putting together a doc based on the initial requirements and discussions on talk.
