I don't agree at all with the fact that productivity is that far ahead on svelte - much of the react productivity lift is with the extensive support from other libraries and platforms. The point about it being more efficient in terms of performance certainly rings true but to claim that it's 2x as productive (twice as fast to get something out in svelte) than react, to the extent you've graphed it in the introduction, is a fabrication. I've seen 2 year old actively-developed svelte projects with so much shimming baked in to support common components that the dev teams essentially have their own toolkits just to work with it. That is not what I would consider 2x as productive. It is an age-old paradigm of "less features = quicker" that at some level of required complexity does invert. It's not a static "this is universally faster" equation.
