This had actually slipped my notice since I rarely, if ever, slot either policy, but that is strange.
I know that they changed Martial Law to apply +2 Loyalty to cities with garrisons, so it is now differentiated from Propaganda, but at least slotting both of those did serve a purpose.
Total War was meant to be an upgrade, but now it's just a lateral/name change. :T Seems like an oversight.
It also reminds me that it seems somewhat silly that Civil Engineering still makes Limes obsolete, even though walls themselves are now made obsolete with Steel.
