I'm probably just wasting my breath here, but truly "zero advantage" to this system? It is simple, requires nothing more than your climbing line and some forethought. Will it work in every situation? No. But neither will half the tools you carry to the job in your truck.
Jack, if all you have to do is unclip your lanyard to facilitate a rescue that can be done even with a pretty severe injury and is generally faster than the fastest climbing rescue. You are getting to that age where you could indeed need rescuing on tree entry, think heart attack, stroke, aneurysm... Let along struck bys and bees. And when in an injury situation, it is nice to have choices. It is always better to not limit your thinking or your choices.
