Yes sir, I'm using the method which is the topic of this thread, the new chain is temporarily attached to the old chain and fed through the engine and finally riveted together.
To my understanding any other installation method is 10 times more effort

Most likely, but you get a good look at all the guides, sprockets, and the tensioner.

Makes me glad I'm no longer trying to make a living wrenching on them.

Just completed second chain replacement. I made one improvement to the process. Instead of removing the cam cover with a slide hammer I used a 1" PVC coupling tapped with a dead blow hammer into the opening for the vacuum pump. I did need to sand a slight chamfer into the leading edge to get it started straight. This was far faster and IMO less risky than the slide hammer route.
