No idea if any “substantial" thing has been written (there are some phds around that may talk about), but main difference is very simple to explain: first approach (which was the same for Pharo before) is non-deterministic while the second is. Then, for purpose of repeatability of process (and testing, etc.) bootstrapping is better. You would not know the amount of effort made to make this possible, it required at least 2 phd works and a considerable amount of engineering effort. In our community, Pavel is the person that has the bigger experience on shrinking process images. I followed his work for years and I know the fragility of the process. Basically each new addition/removal was breaking it and needing dependency tracking, etc. Now is the opposite: you just add what you want, and you are sure the resulting image is a) healthy and b) identical when running.
