+Having "split" terms or equivalently "signed" +-reference terms would\r
+allow more general thread splitting, effectively updating (via a little\r

+file.\r
+\r
+The implementation cost could not be that much higher than only\r
+join/unjoin; a bit more work managing the terms attached to a document\r

+\r
+Both versions probably complicate some peoples syncing solutions.\r
