From an alternate "not the web" viewpoint, I am interested in this because we have a desktop application that bootstraps a lot of JS for each view inside the application. There is a non-insignificant chunk of this time spent in parsing and the existing methods that engines expose (V8 in this case) for snapshotting / caching are not ideal. Given the initial reported gains, this could significantly ratchet down the parsing portion of perceived load time and provide a nice boost for such desktop apps. When presented at TC39, many wanted to see a bit more robust / scientific benchmarks to show that the gains were really there.
