I got the subjugation casus belli after demanding a tribute but the only possible war goal is assimilation. I tried the console command (war 0 4 wg_subjugation) and it said I declared war on the AI but a war didn't actually start.
Given the IMMENSE penalties for going over the administration cap this means robot consciousness (at least assimilators) are a pretty bad choice IMO because you will always have to directly control your territory instead of getting resources from your vassals
