I seem to observe that people drawn to rust are into systems programming and people drawn to rust are into minimal services programming and any attempts at building a batteries-included CRUD framework are so against the grain of the community’s common interest that it never goes anywhere.

Ruby, meanwhile, optimizes for programmer happiness and Rails optimizes for programmer productivity. What other language-framework ecosystem has the same values alignment?

Makes sense. My thought is, while Rust shines in a low-level setting,(Systems programming, embedded, performance-sensitive scientific computing etc) it has enough niceties that I want to use it elsewhere. Package management, enums, result and option types, clear error messages, expressive data structures etc. These are (to me) not enough to make up for the lack of a batteries-included web framework.
