Playing around with 0.97 some more, I think it would be a good idea if the Sindian Diktat crisis allowed you to saturation bombard Diktat worlds without the usual dropping everyone to hostile.
It seems odd to me that the Diktat can just get away with attempting to saturation bombard YOUR worlds with impunity - other factions only do this if you settle in a system they claim, and they immediately stop if your colony grows to size 5, because then that would be considered barbaric. But here the Diktat will happily bombard your size 5 or 6 fuel planet, without even a somewhat-justifiable casus belli, and suffer no penalties to anybody. If they're not beholden to the rules, then why should the player be punished so steeply if they do a retaliatory saturation bombarding of Sindria?
Either punish both, or punish neither.
