I've read through all so far, and thought about the technical points.
Nobody mentioned, the power of having good morale, on a big project; I was actually stunned to view the first 'launch booster return', thinking that "...things are really moving and exciting lately!...".
It's kind of a paradyme shift, freedom from the whole set of hassles when trying to refurbish safely. Plus, we still have the pre-existing way of doing things, using parachute sea landings and all the methods and designs.
Technology amatuers watching a landing get to be 'inspired', that electronic control systems can really perform, in big real-time projects.
So you get a confidence-inspiring visual, and...maybe some planners are checking what it would take, to include human passengers in some novel type of re-entry to runway function.
Like a cheap emergency evacuation system.
More options, and inspiring landings ...to the extent that they look like fake landings, (by playing video backwards).
