Yes, this is along the lines of what I'm suspicious of too, as an also-gamedev that has done some ECS. It's too easy to study an existing system and, given the resources, create a perfect demo for how to dramatically improve it in certain ways. You can go on to ship the demo, but the demo wasn't made by the same kind of organization, with the same kinds of goals, as the original system builders. The extreme example of this is, of course, the demoscene and its hardware-bending tricks that achieve the impossible through a significant modification to the design of a "production" equivalent. So it's better by performance metrics, better by codesize, but unknown on other metrics. Like, "do I know how to start building new things with this?"
