That was under Zah's reign as commander. He got disthroned by Grord due to some shiesty stuff, and now Grord is gone. Not sure if there is a new commander, but if Zah makes a (would this make a third time?) push for it, we may see a no hold's bar approach again. While battle wasn't actively taking other cabals items, it was not uncommon for them to fight a pk under the Watcher or Lich.
Also, you're original assessment is pretty accurate, no mortal leadership has really been pushing the boundaries as far as wars go as of late.
I would add Trib vs Entropy to your list.
