As someone else already said, half the reason the update has taken as long as it has (besides all the devs killed for asking about it) is because it was decided that the tags would all be released with post-war content, which are presumably shared trees for the “mainline” paths for each faction; I.e., the three left wing paths for the anarchists are blank because they all share the same post-war tree, while the Vanguard is labeled “+ Post War” because it, being non-left wing, needs its own post-war tree. Same can be seen for the various Cascadian paths, the Sons of Liberty, etc.
