They're similar, but seem to have fundamental differences in that the Hive variant requires a different dinension

Not necessarily, I think? The three wizards you fight in the Court of Oryx "hid their deaths" in each other rather than in an alternate dimension, and Kagoor hid hers in her Servile Ogre. that might be something unique to Wizards, but it's seems very similar to the Guardian/Ghost dynamic.

It might be something different though, just a way to quickly be resurrected rather than returning to your Throne World first.
