Tim, I wondered the same thing but my experience with various rigs is limited. When I got my TS-2000 I was surprised with the relay switching it does.
Perhaps the devices that can replace the old RF switching relay are not so long-lived? At any rate they also have a finite lifespan so we should take that into consideration when considering fast switching modes.
