Even though every situation might require that you improvise a little, having a basic recipe and understanding of s/r to start with is a good idea. Without a basic understanding it's not a good idea to attempt to just figure it out on the fly.
I am confident that many riders are very lacking in what they know in terms of self rescue, including me.
Jim is a smart guy, but this stuff needs to be taught to be learned.
I think Jim's idea of having a few people have a self rescue orientation is a good idea. It won't be free and shouldn't be. Maybe Steve S. or someone else with such training could set this up at a reasonable fee,kind of on the fly out a EB one day, near the end of a day after we have our fill of riding (?).
