I interviewed there and asked about this and they said their coordination server and (and other UI features UI) are almost completely about satisfying very demanding enterprise customers, with one of the major concerns being the performance particularly of applying ACL rules across huge complex networks. They said there would be a lot of code cleanup to open source the coordination server, and it's not been completely ruled out but Headscale is such a nice alternative for those that care about an open source coordination server that it doesn't seem to be a big motivation.
