I agree that Semiotic serves probably 80% of data vis use cases in real world. But at the end of the day it is a high-level template-based library that's less expressive than D3. If you take a random vis from observable's "trending notebooks", chances are that it is not reproducible with Semiotic. Those two libraries are really for different purposes.
